Additional context
It may be because I am currently messing with the css a lot and stuff

I am currently working on debugging this with the Thonny IDE and the current issue is that it cannot edit the drive.

From my experience, your error only happens if you have USB mode enabled and try to modify a file

[Computeroid]

You're right. For my purposes I need USB mode enabled so I just deleted the drive mount lines in create_new_script() and added a try-catch. It's not 100% safe but it works for me as I have backups.

If USB Mass Storage mode is enabled, then the webapp cannot write to the internal flash. this is a limitation of circuitpython.

As for the original issue, do you have an example script that causes the problem? I'll try to take a look at this issue in the next couple of weeks.

[XtramCZ]

Nah, I haven't noticed this happening with a particular script, but it happens more with longer ones
