[posila] Game loads, loading screen glitches and game crashes

[k_is_king]

Whenever I launch the game through steam the game shows the regular loading screen. After a while the loading bar disappears and only the letter "L" shows up. The loading bar disappears and only some numbers (which I assume is the percentage of the game loaded) show up, although they're glitchy as well. I didn't take a screenshot of this, and now I can't because the game loads about 46% without the loading screen glitch and gives the error shown in the log and screenshot below.

If anyone could please help me fix this or tell me the cause I'd be grateful. Thanks in advance.
