this behavior was observed it Julia 1.8.1 and was related to number of threads for openblas during precompilation, see for more details:

It started off with failing precompilation via LoadError when trying to add a package and has now progressed into either locking up/freezing my OS or crashing say, firefox due to random errors while Julia is attempting to precompile packages.

You can either update Julia to the newest version (1.8.3) or change the environment variable mentioned in the thread. Let us know, if that solved your issue.
