Thanks for checking back, but the other comments mentioned tweaking ProtonTricks and that got rid of the error.

Thank you so much. This worked like a charm but now that the error is gone it tries to launch the Rockstar Launcher but crashes without any error messages.

Oh wow, I don’t know hos I missed this post on Proton DB, but thanks for posting it here. It got rid of the error but now I tries to launch the Rockstar Launcher but doesn’t launch either.

Sorry I didn’t mention, but I am using Steam flatpack.

I already tried to install those, they’re too old to even install. Thanks for the reply anyway.

True, but might as well put up a good fight while we’re at it.

Google is actively trying to drive people like me away. I have been trying my hardest to keep using Android, if Google keeps this up I might have to unwillingly move to Apple. At least they do more than just pretend to care about their users’ privacy.

Oh! true, completely slipped my mind. Install it in another PC or use an M.2 enclosure with USB C to partition it and clone the original.

I don’t own a Steamdeck myself but since it’s Arch Linux based there should be a partitioning tool like GParted built in.

You may want to check if it is partitioned.
