Hey, I’m unable to reproduce this bug (with 3 PCs so far) but my players keep reporting it over and over. I requested them to send logs but unfortunately there’s nothing interesting. The worst part of this bug is that game is frozen completely and users are not able to even open Task Manager to close the game :(.
Quick google search shows that this problem also exists in other popular games like Escape from Tarkov and Rust so I believe this could be engine error.
Edit
It looks that bug is gone after disabling “Run in background” build option. This isn’t really proper solution for me as PlayFab by default sets this option on as otherwise it may cause issues.
