Sorry to hear you are running into this issue. Do you encounter a "Something went wrong" error like shown below:
Or a different error or crash? If so, could you include a screenshot? The URL of your file (from the browser's address bar when the file is open) can also help us investigate further.
I don't get an error message. The suggested fonts group under text just starts to flicker and then the whole computer freezes and I have to restart the program. I deleted the uploaded fonts and it has stopped. It must be one of the fonts causing the issue.
