Bike resting in front of air conditioning
Is there anyway this would be a contributing factor to a brand new I believe properly installed tube that has not been ridden?

Yes. doesn't matter whether it's been ridden or not.

Um, cold air will tend to reduce the pressure inside of the tube/tire. You can neglect any shrinkage of the rubber due to temperature.

This is what I thought but wasn't sure if there is some unintuitive occurrence with rubber pressure vessels that are contained against a rigid wall.

Remember that thin rubber wall isn't impermeable to air. Don't underestimate user error either.

I've had so many problems with the front wheel with flats including 2 brand new tubes never being ridden failing. I know a lot have been due to bad installation and low pressure. Last night after it failed one of if not the only times the rupture has been on the inside of the tube. I inspected the rim tape and in the area it was off center but I didn't see/feel an area that would have compromised the tube.

Do you check the air pressure before you ride it? If I go two days between rides, I check and give my tires a stroke or two of the pump. If you go a long time without moving your bike, then roll it on a nearly flat tire, then air it up...... you might have issues.
If the pressure gets low enough to let the beads break from the rim, then there is some care that needs to happen before and during inflation. I've had bikes in storage, and when I rolled them just a little to get them in a better position to lift, the tires came off the rim.
...... notice the correlation..... more words from you per post.... more words from us. <grin> Just a friendly jab... don't take it as mean.

I have checked since I have had so many issues over time but for awhile there I only had a hand pump that could only achieve 60 - 80 psi. These are 700 x 23c tires I have recently picked up a floor pump and been putting the tires to 90-110 trying to find a good pressure. I typically using conti tubes but the local shop has run out so I tried Q tubes is the brand I believe which is where the failures without riding have occurred.
I also remember seeing Kendra branded on the tubes in the box so might have the branding wrong

60 psi is way low for a 700 x 23 tire. 80 is arguable depending on total ride weight. As you've found, a floor pump lets you get to the higher pressures.
Butyl or latex tubes? I've used Continental tubes and other popular brands of butyl tubes. But for the riding I do, I don't need the weight savings or the additional suppleness they add to my ride. So I just use the cheapo Bell butyl inner tubes I find at the big box discount stores in the bike section. I don't get the thicker puncture resistant ones though. Those would be too harsh riding, heavy and hard to install, for me.
If there isn't an installation error, spoke or sharp place in the rim. Nor a wire or thorn poking through the tread or sidewall, then maybe a tube less highly regarded by those seeking high performance might help.

Q tubes are made by Kenda and are lower priced than some. I've used plenty of their tubes and never had a problem but every so often a mfr. can put out a bad batch.

This has definitely been a process but since I have also only ever owned Walmart mountain bikes as a kid. Granted this bike isn't that much more (City Brand fixed gear I got off Craigslist in great condition) but having road tires has been a little different for me. I have been considering going tubeless after all the issues but know plenty have great performance from the tried and true.
Need to try also just replacing the used gatorskin on the problematic tire. My rear tire was just replaced with a fresh gatorskin after having the manufacturer Unbranded tire that wore out from riding along with the very occasional skidding I would do. That tire thankfully only had a few flats since it's more of a hassle to swap out.

Tubeless might be an issue if you don't ride frequently. Consider letting a bike shop take a look at that wheel if you haven't already. And if the do or did and it gives issues afterwards, go back. There are all kinds of things that can be not readily apparent, even by the best of tire changers.

This wheel was recently replaced by a local shop so after this last night I decided I should take it in to have a follow up since the rim tape doesn't look like the greatest application. I ride nearly every day anywhere from 10-30 miles and there has been occasions of a few days to a week break depending on how I feel and the weather. Those days I have made had a look over on the tires and have not noticed anything.

Did you originally get a flat from a puncture? if so, a glass shard or thorn might still be in the tire casing and giving you a slow leak puncture. Take off the tire and run a cotton ball around the inside to check if anything snags the fibers. Be careful doing it by hand as I've cut a finger on a glass shard. If you find anything, remove it before installing any more new tubes.

2 flats with no riding 1 tube had a preety extreme bottle neck at the pout where the valve attached which had a pin hole. The other was on the inside of the tube and the rim tape was a little wonky but no sign of anything.

Almost every flat on the road I can identify hitting a pot hole, object, rough road patch or blunt edge with each having a "snake bite" failure in the tube.
2 flats with no riding 1 tube had a preety extreme bottle neck at the pout where the valve attached which had a pin hole. The other was on the inside of the tube and the rim tape was a little wonky but no sign of anything.

Spoke hole was close to being exposed but could have shifted enough. So might redo the tape to eliminate any potential.

As previously mentioned I recently picked up a floor pump so hopefully just a bad lick with these recent tubes and will be good for a bit fingers crossed.

Check out where the hole in the inner tube is relative to the valve stem hole in the rim. If it looks like they might match up, that's it.
