-- Information about the crash:
I've been encountering the issue for a while now, but I'm pretty sure it's
gotten worse since upgrading the CPU and going from 16 to 24 physical threads.
It seems to be always reproducible when attempting to include a file and the
parser is working (i.e. the progress bar on the bottom right is shown).
The program freezes while typing and crashes after some time.
The crash can be reproduced every time.
