Games Crashing Randomly

[storyjesse]

As it says above. I'm now able to post the detailed output from the terminal which I couldn't figure out how to post earlier.
If anyone can take a look at the output I'd be very grateful. I notice the

ERROR: ld.so: object[\code] and 
(wrong ELF class: ELFCLASS32): ignored.[\code] Can anyone shed more light on what that means?

This issue isn't isolated to Dungeions3, it also happens in Lego Bricktales and other games but Dungeons3 is the game I've managed to capture terminal output from.

I'm running Steam as Flatpack

Sometimes the crash occurs after 15min sometimes after 50min.
I tried reducing the resolution and turning down all the graphics options but the issue still occurred.

terminal output to follow:

This terminal output is from starting steam to the second crash. Only the game crashes, not steam its self, and so after the first crash I restarted the game and played until it crashed again.

All help greatly appreciated.

P.S. When I tried to post this question I get an error message "There was an error creating a new topic: 2" :-/ So I created this topic with a short intro. Then after it had been approved I tried to post this output. I got a better error message telling me that I had exceeded the limit of 18000 characters. Would have appreciated that error message originally.

You should take this matter to the Steam-for-Linux forum.
