Trouble launching Fabledom

I’ve edited the topic title as the original was completely erroneous and misleading.

I understand that i wouldn’t use “Proton Bleeding Edge” or “Proton Hotfix”.
This are Beta Branches around Proton Experimental. From the error at the Topic, it looks like that OP had activated this Beta Option. :man_shrugging:

But i will keep using “Proton Experimental” (non Beta) because its running for most of the games that i played in the past, just fine.

Anyways, thanks for the link…i wasn’t aware that Proton Exp. has additional options.
