Some 1x setups have chainline issues.

If your bike frame is spec'd with a road group but uses an MTB hub, the hub chain lines are different. Road is 41.5mm while MTB is 44mm. This pushes the chain 2.5mm further outbound and can create problems like loud, clattery drivetrains, chain drops, chain slips or it can decrease shifting performance.

Have a look at your chain line and see if it is the problem or perhaps a contributing factor to the problem.

Good luck.
