1x9 Bliss and Blues
I love my simple 1x9 super commuter/errand bike! However, 95% of the time, when shifting into the smallest/highest gear/cog, the chain runs off the front sprocket and gets caught in the chainguard. Very frustrating, to say the least! Please help! Thanks in advance...

Get a narrow wide chainring. Also make sure your chain is not too long, as that allows more chain bounce when shifting or hitting bumps.

What kind of crankset is this (dedicated 1X, or a converted 2X or 3X)? And if it is a converted 2X or 3X, what position is the ring on now?
Is the ring you are using a dedicated 1X ring (such as a narrow/wide)?

why not put FD back on and use it to keep the chain on the chainring.. ?
run the stroke limit screw in to center it over that 1 chainring

You are going to need to give more details.
How much USE is on the chain and ring? Does the ring look worn down? What kind of ring is this? Pics? I dedicated 1x ring should not be dropping. Does this happen AS you shift? Does it matter if it is bumpy? Have you checked the chain for wear?

Is it the Haanjo Metro? I have a Haanjo Metro, and the chain falls off when on the smallest cog, but only when I backpedal. I can live with it, but would be interested if you find a satisfactory solution. It happened when the components were still new enough to have minimal wear.

The easiest thing to try would be to adjust the derailleur tension B screw. That and the chain length play together to keep the right amount of tension in the chain.

I had the same issue, though infrequent, on my 1x11 road bike. Shimano 105 in the back. Solved the issue to my comfort with a WolfTooth Drop-Stop narrow/wide chainring. They are a bit pricey. I have added one of these to my toolkit for good measure.
Other things to check: Is your frame aligned properly (specifically the rear triangle). Is the RD hanger aligned properly. Adjustment of RD may need some tweaking. Easiest may be the chain - perhaps you have too many links. shortening will increase tension and that will lessen the chance of chain drop. Certainly replace the chain if worn.

On a narrow wide chainring the teeth are taller, and alternate in width to match the width of the chain links. For this reason they are only available in even tooth numbers. When you look closely at one it makes sense.

Is the chain falling in between the chainring and the ring guard on the outside, or going over the guard as well?
When I run a bash guard on the outside of my single ring, one of the benefits is that it pretty much prevents the chain from dropping the chain to the outside.

Pre Indexed shifting Chainrings also have full height teeth , friction shifting skills made them work fine even with more than 1 ring..
another option Surly Stainless steel chainrings ,they're reversable to double the wear life too..

I might try one of those narrow wide rings. Fortunately my only use of the small cog is going downhill, since it's actually above my top end speed on level ground. Between being a pretty slow cyclist, and the aerodynamic penalty of having a relatively high riding posture, I'm never going to be a speed demon on that bike, though it's the fastest bike I own.

Same as mine. It's not a clutch derailleur. For the sake of others, here's the Haanjo Metro. Yes, mine is bright yellow:

The drivetrain is relatively entry level, though mine has functioned flawlessly except for the issue noted in this thread. For me, it's been extremely comfortable and fun to ride. It's my only multi-speed bike right now.
