--- Comment #4 from Harold felineswift+wine@gmail.com --- UPDATE: Ignore all the logs above. My Lost Ark installation was on an NTFS drive which is known issue in Proton. After moving the installation to ext4 drive Easy Anti Cheat logo and Lost Ark banner appeared, then C++ exceptions / SEH exceptions started to spam (i'm bad at deciphering those).
Log is pretty big so I'm not attaching it but maybe this line is relevant:
