Trying to get the game running on Bazzite

My girlfriend wanted to get back into the game, and wanted me to tag along, but since the last time I played I made the jump to Linux from Windows. I can get the game up and running just fine, but after some time I get kicked from the game for 'suspicious client activity'. Looking for any help towards getting this resolved so I can actually play.

I'm on Bazzite, have the game running via the nexon launcher through Lutris, using Proton cachyos-11.0-20260703-slr. Any help appreciated.
