Steamdeck Crash to Blackscreen

[Zender]

I recently got a steamdeck off of the summer sale and it's been working great until the past week or so.
Randomly when I'm running a game (mainly Remnant 2) it'll randomly crash to an unresponsive black screen.
I've kept an eye on the temperature and it rarely gets above 70C.
Does anyone have any ideas or advice for troubleshooting this?

I have a similar issue with Eldenring since a few days. Plays normal for like 20 minutes then the screen freezes with sound still going. If I don‘t force-close the game by Steam+B the steam deck crashes completely.

I gave different proton versions another try. I Found one called
"proton hotfix" at the end of the list, downloaded it, started Eldenring and played 1 minute until it crashed again. Then I did a reboot via steam menu. After the system started again I went into offline Mode and tried Proton 7.0-6 and didn't had a crash for like 40 minutes.
Update: After going online again it seems fine now and even after another hour of play time theres no crash yet.

Maybe this could help.

Just to add to that, my crashing seems to happen most when I have a third party app running in the background (Discord) alongside other apps, so you just made me think about something
I'm going to try reinstalling it, then I'll update if that works, because maybe it's just a one app problem.

Almost forgot to update you, but it didn't fix it, it just lessened the amount of crashes

I‘m sorry to hear that the issue still persists on your side.
On my site everything is fine now :/
One thing that I also did was installing CryoUtilies with the recommended settings. - forgot to add that.

I haven't touched Cryoutils at all
I haven't actually seen it before either, so maybe that's my problem

I'm not sure how I fixed it, the issue just isn't happening anymore, so unfortunately I'm not sure I can help
I think I know *why* it went to a black screen
Sometimes when it does that it opens up the lockscreen, so my theory is that it tries to lock the device for some reason while it's in use, and so the screen goes black since it thinks you're hacking your way past the lockscreen. But that doesn't explain how I fixed it considering that I never turned off my steam deck's passcode
