Precompile failure can cause a Pluto notebook to stop responding; `using Profile`

[BioTurboNick]

I believe the error itself is unrelated to Pluto, but it's causing the notebook to hang (working animations running). Pluto v0.19.0, Julia 1.8.0-beta3

It seems to be happening when I try to add using Profile. The only way to get out of it is to edit the notebook manually to remove that line, then restart the notebook.

We should create a package that always errors during precompilation and add it to https://github.com/JuliaPluto/PlutoPkgTestRegistry to debug/fix/test this.

I created https://github.com/JuliaPluto/PlutoPkgTestErrorA.jl and added it to https://github.com/JuliaPluto/PlutoPkgTestRegistry.

I'm leaving the rest as a Good First Issue! Search for PlutoPkgTest in our source code to learn more about writing package manager tests.

Not sure if it is related, but I was trying to test Pluto for the 1st time, and it partially hangs in the welcome page as below The 2 first menus are responding though. The 1st one goes to different examples, but none is accessible (blank page forever); while the 2nd one "create a new notebook" leads also to a blank page. The console does not say anything beside "... have fun" and "ctrl+C and updating registry done".

A ctrl+C sometimes yields

      From worker 2:    fatal: error thrown and no exception handler available.
      From worker 2:    InterruptException()

Hope this helps.

@sylvain-bougnoux Can you make a new issue? A screen recording would be great
