Game heavily dislikes VPNs, firewalls, probably so the Easy Anti Cheat can kernel into your PC and read your cpu usage/memory and what files your running whilst playing.
I read you already tried step 1) Verify Files
Step 2) Un-install / Re-Install
Step 3) Flip the table, jk. Probably double check firewall/vpn/router settings but honestly I’d just do Step 2) first.
