Bumping react-scripts from 3.3.0 to 3.4.0 solved the problem, per https://stackoverflow.com/questions/58199001/typeerror-err-invalid-arg-type-the-path-argument-must-be-of-type-string-re

Hi @liamCorbett

first of all sry. for my late reply and thanks for pointing out the issue.
I just updated all outdated npm dependencies and bumped react-scripts to 3.4.0.

So should work again 😁

Please let me know if you experience any other issues - otherwise I would just close this one.

Best,

Jan
