I did that, but it did not produce any logs either :(

I did not try that, but I did try battle.net tjrough bottles and I get a similar issue. Does not launch , no errors.

the only thing I saw was changing some launch options, and none of the mworked unfortunately.

Deleting the bottles directories from the repos directory seems to fix it, thanks for the advice!

Update: Following your advice, I proceeded to delete the files for “bottles” from the repo folder in /var/lib/… and that seems to solve the issue! thanks for the help! :)

thanks for the tip about storage space, although I do seem to have 100 GB of free space so I do not think this is the issue?

However I noticed I have a filesystem /run/user/1000 it seems to be created by flatpak, and it has 1.6 GB of total space. Should this be a source of worry?

The other advice about deleting the directories does not seem to work either :(

I did try multiple versions of proton, but still without success and same issues :(

If important to verify, I have my logs from running steam in terminal here:

Some of those might look a bit conerning but they seem to show up for games that work also.
