No Games Launching Using any Proton(Ubuntu 22.04 LTS)

[pommyraj]

So I have been trying to play games (such as Arkham Knight,Arkham CIty ,etc.) on Ubuntu 22.04 LTS but none of the games launch.It just shows processing vulkan shaders and then when it is complete the launch stops own its own.The only game I have been able to play is CS:go. Heres what I have tried so far-
1) Updating my drivers.
2) Using all the Proton versions even custom Proton (GE to be specific)
3)Uninstall and install the game and steam as well.

When I use proton hotfix I get the error mentioned below.I have tried using a exFAT drive and an ext4 drive.

THE ERROR- An error occured while updating Batman :Arkham Knight (disk write error):
/media/kawish/New Volume/SteamLibrary/steamapps/downloading/2180100/files/lib64/libdav1d.so

Output of "mount" could help.

example if /media/kawish is mounted on let's say /dev/sdb1,
then search dmesg for it. "sudo dmesg | grep /dev/sdb1", if there are any errors with the filesystem.

What does the following say?
"file /media/kawish/New\ Volume/SteamLibrary/steamapps/downloading/2180100/files/lib64/libdav1d.so"

Do you have write permissions?

Is there still space left? ==> df -m

Are there still inodes free? ==> df -i

And I'm suspecting the folder "New Volume" or "New\ Volume" making problems - MAYBE.

PS: No need to mess around with exFAT. ext4 is fine. Also without the whole not-case-sensitive stuff. Just standard ext4 is fine.

also maybe ask steam to clear download cache (there is a button in steam settings for this)

Have you found a solution to your problem ?
I'm facing a similar issue : I run a game from steam, I see "launching" then "running" written in steam, then nothing. Literally nothing.
