any advice will be more than welcome as Im using mainly Makie but also GLMakie and there are 3 Plots dependencies:
after "add GLMakie": all compiled except:

I opened a separate issue #4968 for a similar FFMPEG error as @WuSiren , except on Julia 1.10.4 . If I find a fix in that thread that applies to 1.10.3, I'll mention it here too.

[elesar50]

Hi I just installed Julia 1.10.4 on the same laptop but on Ubuntu 24.04 (I installed it alongside with windows as dual boot) and compiled Plots without any issue.

[hydrosquall]

I closed the other issue thread as restarting my computer (and by extension, the Julia session) fixed my installation.

[RohanRajagopal]

This fixes the issue on Windows, if anyone requires a solution. I don't know if this is a robust fix though.
