Seems like the hardware is sufficient to run HA, so then it is a question if it is the hardware or the addon causing the crash.
Does it crash if you are not using the RTL_433 addon?
If not then you should try to direct the bug report at the RTL_433 addon GitHub page.
I can’t actually confirm this is rtl_433’s fault. I’ve been experimenting with a few addons, so unsure how related it is.
And in fact, today I just logged into HA to find the supervisor is unresponive even when doing none of the things I was doing before that I suspected was causing the crash.
