'ValueError: 2307:2222: not well-formed (invalid token)

I've been working in jupyter lab with the package threeML, as of last night everything was working fine when my computer crashed with the Jupyter servers still running. As I tried working with the same file, I get an error when trying to access the catalog data: gbmCatalog = FermiGBMBurstCatalog(), generating the error of the title:

...
ValueError: 2307:2222: not well-formed (invalid token)

Running other parts of the code works fine such as importing packages, I did notice a couple of Jupyter servers running in the background which I finally managed to close. I first got a warning I've not seen yet when starting my jupyter session, not sure how relevant:

[W 2022-04-29 10:16:14.855 LabApp] Could not determine jupyterlab build status 
without nodejs

I tried installing nodejs in my env, reverting back to the exact env which was working correctly last night, restarting the computer. Now, I'm not familiar with XML which seem to be the questions popping up in regards to this kind of token errors.
