Weird error in GitHub action: ERROR: LoadError: KeyError: key "PrecompileTools" not found

I m trying to push a newer version of a package on GitHub. It tests fine in local, but on github actions I have the following weird error:

I have even removed the using PrecompileTools and commented out the PRecompile.jl stuff, but I still have the error.. just to have PrecompileTools = "1" in my Project.toml file!
What the hell could be ?

This is really weird… I removed EVERYTHING of PrecompileTools, not in the Project.toml of my package, not in the main environment, nowhere… but on GitHub action or in local using Juilia 1.9 I get the error:

Where julia is trying to get it from ???

Even MORE weird.. I reverted to a commit that was working, and now the CI action is still creating this problem…

ugh.. this must be related to Ipopt release 1.10, 13 hours ago:
