How do I fix this error?

1

It suddenly appeared after a reboot, and now I don’t know how to make font exportable again.

Can you send me the file?

You should still have access to the Github repository where the font is located.

I just uploaded the latest changes, which this error occurs with.

Were you able to gain access to the latest iteration of the font, or should I compress it as a zip file and share that with you, like I did previously?
