Twine 2.1 crash

Twine 2.1 crashes every time I open it. The window stays for a few seconds: I can see the icon and the menu bar, and then it closes. It worked for a while before, but words and brackets weren't being highlighted. I don't know how to recreate the problem, either.

Here's the error message from the debug log (it looks like a memory error or something):

[0206/162053:WARNING:process_subrange_reader.cc(59)] range 0x1400e3000 + 0x48af8 (64) outside of range 0x140000000 + 0xf4000 (64) for C:\Users\[USER]\Documents\Twine\Twine.exe resources

Any suggestions?
