Hello. Same problem. Just adding my voice to the pile.

Tried playing around with the game config and wine settings, uninstalled, reinstalled, tried through Steam Proton to no avail.
Thought about patching the game through a virtual machine then copying the files over to the host and using a custom launcher, but I ran into a myriad problems with the custom launchers themselves.

Basically unplayable as of the latest patch. Bummer.
