Every time I load into the game Arena, it launches in windowed mode. I have tried various graphic settings, but none have resolved the issue.

I'm unsure how this problem started occurring.

System Details:
OS:** Windows 11 Home
System Model:** X570 AORUS MASTER
System Type:** x64-based PC
Processor:** AMD Ryzen 9 3900X 12-Core Processor, 3.8 GHz, 12 Cores, 24 Logical Processors

As mentioned, every time I load Arena, it defaults to windowed mode. Even after I manually switch to full screen in the main menu, it reverts to windowed mode when I start a game. The same happens if I change the setting during a game; once I finish and return to the main menu, it goes back to windowed mode.

I have also uninstalled, reinstalled, and repaired the game files, and all my drivers are up to date.

Unfortunately, I have not found any workarounds for this issue so far.

Thank you!
