Symptoms

Upon launching the game, a variety of error windows appear. The mouse disappears as one hovers over them, are closed by pressing the enter key, and repeatedly appear until I reach the main menu. Starting a new game produces yet more error windows, and these continue appearing as the game loads until it finally crashes.
The error windows below are shown in the order they were presented on one launch, although most reappeared several times.

Reproduction

I have only tested this in Proton Experimental and 7.0-3, and on one computer, but it happens every time I attempt to play it. The error messages do not seem to appear in the same order when relaunched or especially upon starting a new game, even within the same Proton version, and one launch produced error messages with two or three letters appended to the end of several otherwise identical error messages.

Start by reproducing SOLAR BATTALION under Proton Experimental and 7.0-3, then inspect the attached steam-803570.log and the reported error screenshots. Done would require identifying the compatibility cause and confirming that the game reaches and loads a new game without the repeated error windows or crash.
