` AssertionError: isfile(f)` on Windows 10 with Julia `1.9.1`

On a clean environment:

My system is Windows 10 (Fully updated), Julia 1.9.1.

Caught this using Bokeh.jl: https://github.com/cjdoris/Bokeh.jl/issues/26.

What version of Blink is this happening for?

[RoyiAvital]

I guess the latest. I just added it to a fresh environment.

[mzaffalon]

Hit ] and when the prompt changes, type st.

[RoyiAvital]

What I get is: [ad839575] Blink v0.12.8. But I did some operations since the issue.

Why, was it known on other versions?

[mzaffalon]

Not that I know and I cannot reproduce the error.

[RoyiAvital]

Could be pre compilations of 1.9.x thing? I will remove compiled data and recheck.

[RoyiAvital]

I removed everything in .julia\compiled. Still got:

[RoyiAvital]

OK, I had to clean: artifacts, compiled, packages and scratchspaces. Then installing and precompiling worked.

I guess some issue with the precompilation or something.

[jonCAstickel]

I am experiencing the same error on Ubuntu 22.04. Deleting all of artifacts, compiled, packages, and scratchspaces seems a bit excessive to me as a solution. Any ideas for a more tidy cleanup to resolve this? FWIW, I get no error if I restrict Blink to 0.12.5.

Edit: when downgrading Blink to 0.12.5, using Blink prompted me to build WebIO. Doing that, and then upgrading Blink back to 0.12.8, has resolved the problem for me. Hopefully this helps someone else.
