--- Comment #3 from lyon@pvfree.net --- Interestingly, the Proton changelog from Jan 17 states: "update wine to bleeding-edge (fixes battle.net broken updates)" https://github.com/GloriousEggroll/proton-ge-custom/releases/tag/GE-Proton9-...
Not sure what this "bleeding edge" is but it looks like Valve's fork which Proton uses.
The relevant Proton commit is this one https://github.com/GloriousEggroll/proton-ge-custom/commit/3367b11bb49c086ec...
This leads to a few crypt32 related commits that seem to have been backported to vanilla Wine on Jan 22: https://gitlab.winehq.org/wine/wine/-/merge_requests/7117/commits
This make sense as I've seen at least one forum post related to a BLZBNTAGT00000840 error versus certificate issue from a Windows 11 user and the crypt32 module changes seem to be certificate related.
As I can't do a Wine rebuild right now I'll wait for the next official build that I believe will fix this bug.
