The appinfo.vdf version might not be supported by the current version of Protontricks

[ademarest]

Steam released a new build today.
When attempting to select any steam app protontricks complains about appinfo.vdf and crashes.
This happens on Fedora 40 and Archlinux.
Here's my Steam about section. It is a stable build.

Terminal output regarding the syntax error:

I got the same errors. Literally can't run apps under protontricks anymore.

Edit: Tried downgrading, or switching to non-git version. Still errors.

@ademarest @Heisenborgar The workaround/fix here worked for me: #304 (comment)

Thanks @d3-X-t3r Honestly mine was working fine until I updated protontricks this morning

As stated, the beta version of Protontricks has to be installed per the instructions. There's also a notice in the header of the README.
