Symptoms

Until May of 2020, the game was working fine for Single Player games. In June there was an update that made the game start to freeze all the time, also in the menus, except for the main menu. The FPS goes below 1 Hz. Actually it mostly goes fluid for a fraction of a second and freezes for several seconds, including mouse pointer, even when I do an Alt+Tab to switch to another window and start moving the mouse over something else. But the main menu of the game is still fluid, even if it looks exactly like the other menus. None of the updates from June 2020 onwards changed this. At the current state, the game is completely unplayable in Linux.

Reproduction
