Game crashes when it loses focus in Plasma 6

I’ve recently switched from Debian to Arch and I’m on KDE6 now. I didn’t have this kind of issue on Debian and Plasma 5.

The issue now is, when I’m on the multiplayer ranked screen (oddly enough only when I’m on the multiplayer ranked screen) in the game Tetris Effect: Connected, the game crashes after losing focus.

I would guess the game needs to maintain some kind of internet connection when it’s on the ranked screen, and losing focus does something that stops the game from maintaining the connection.

Can I somehow keep the game functioning normally even when it doesn’t have focus? This is my first question, so if I need to check any logs, please tell me where.
