Per the title, after about 30 minutes, the game will crash upon loading into a new map or--in one case--loading a sound for an explosion effect. The game otherwise plays perfectly on mouse and keyboard and I have not noticed any other adverse effects.

Game info:
$ ./start.sh -v
1.5.78.11833
51218


Edit:
Since creating this post, I have tried launching the game via `start.sh` in the terminal and via the `Hollow Knight` executable directly--both have yielded the same result, but showed that when the game crashes it does so with this error message:

./start.sh: line 16: 49176 Segmentation fault ./"Hollow Knight"

Try in opengl mode like in another post (hollow_knight_crashes_on_start_libvulkan).

Edit the start.sh script line 20:
