As from yesterday morning, I keep on getting the following error or something similar every time I try to run something involving some Figure on a Pluto Notebook. The notebook also takes a very long time to load.

I have tried updating the Pluto environment with no success. I have also carried out some other updates. Has anyone ever encountered something similar?

Note that I was running the Pluto notebooks a few days ago with no problems.

Hi @kurtspiteri, do you have a small example to try and reproduce the issue? Also, what’s the output of running `versioninfo()`?

Good evening, thank you for your reply. I was running Julia Version 1.10, and was running the following Pluto notebook:

> <https://github.com/weymouth/NumericalShipHydro/blob/main/notebooks/sphere.jl>

I uninstalled and reinstalled Julia (now I am running Version 1.10.2). The original issue seems to be gone for now. I do not know if this has fully solved the problem.
