Notebook gets stuck in forever loading state after restarting my PC while running it

[tholdem]

Pluto was working well until I restarted my computer while running it. Now although I can open old and new notebooks, they are forever stuck in loading state, making it impossible to use Pluto. What should I do?

A wild guess is to delete the C:\Users\bryan\.julia folder and everything in it, and try to restart.
Make sure to keep your notebook files safe. Let us know if that works!

Are you in Windows 10 btw?

[tholdem]

Yes this is windows 10. But C:\Users\bryan\.julia is where all my JuliaPro stuff is installed. Deleting it would delete everything Julia related. I moved my notebook to different directories with no success. Any notebook, old or new, stays in loading state.

Then I tried to reinstall Pluto but accidentally removed it from the registries using ] remove Pluto. I have no idea how to add it back and now Julia wouldn't let me add the package. Could you please help me? Thank you.

[pankgeorg]

My guess is that all these stuff are corrupted - that's why I propose deleting and reinstalling. Can't you re install them?

[pankgeorg]

You should be able to reinstall Pluto using ] add Pluto
Let's talk in Zulip if you prefer

[fonsp]

You probably have a corrupted package registry, you need to delete .julia or at least the registries subfolder. If you're worried about corrupting the installation, then the easiest thing is to reinstall Julia (or JuliaPro if you think that you need it)

[tholdem]

Thank you for the input. That's unfortunate and I think it could've been a bug with Pluto since everything else in JuliaPro is working fine. I will try resinstalling after I'm done using my Jypter Notebook session.
