STARK: Black screen with flashing rectangles when choosing to overwrite an autosave

I've had saved the game three times, using the game's own native save game panel (not ScummVM GMM), and one of my saved games was using the autosave slot. I've left the game idle for a while and I am assuming at what was the autosave interval (5 minutes?) it prompted me with a dialogue to choose if I wanted to overwrite the game saved on the autosave slot. (image attached: scummvm-tlj-win-00000.jpg)

I chose the "overwrite" option, at which point the screen became black and there were some rectangle shapes on the screen that seemed to react (flashing) when moving the mouse. (image attached: scummvm-tlj-win-00001.jpg)

I could not recover the game from that point, nor bring up the GMM, so I had to Alt-F4 to exit the game.

After re-launching ScummVM, the overwritten slot (from ScummVM launcher "Load") looks glitched too (see attached image)

Side bug: Saving via the game's native save game panel, you cannot enter a description for the save game; the game automatically sets one for you based on current chapter and timestamp. However, notice the ScummVM prompt for the autosave overwrite (the attached scummvm-tlj-win-00000.jpg). The game is described as "P" (maybe from "Prologue"?). This seems bugged.
