I've had similar issues, but bought a NanoPi R6S with 8GB ram. Got ubuntu 22.04 going on the first day, and it's a nice little server. It's crazy faster than a Pi4, stable, and runs cool. I paid for the $20 CNC machines case with passive cooling. Under normal use it's quite cool to the touch, and plan to make it into a small home router after I'm done tinkering with it.
