Yep! Using it on Android rn.

I’d honestly be very cautious with anything google. Aegis would probably be a better option.

First os: technically the Wii’s os and android

First Linux: Ubuntu 16.04 (I remember it like it was yesterday 🥲)

That’s about what I would have done. Try to switch to a console first like you did, but if that doesn’t work, force reboot and pray.

The worst that could happen is that you might have some data loss or mess up the OS (which has happened to me before). That’s why you should always have an up-to-date backup! It’ll save you one of these days.

Either way, try switching to a different proton version, or do some other fixes and test it out until it stops crashing. This honestly sounds like a freak (but common) problem. I wouldn’t worry about data loss or corruption that much if there’s no other signs of it (e.g., SMART reporting a dying drive), but a backup is generally helpful for any scenario.
