Pretty much all of those have been issues with regular steamOS at different points. I have to toggle bt on and off for some of my controllers to connect, but I’ve learned that other people have been forgetting and repairing to fix the same issue. The HDMI issue was a problem some months back, but has been fixed (at least on the beta update channel). The recent steam client beta was causing crashes with some plugins, and the newly released bt wake control was one of them.

I don’t know exactly how long you were using Bazzite, but it’s possible that all the issues you’ve run into were upstream issues that made their way to Bazzite unfortunately.
