Cannot compile Unity's domain assemblies because referenced assemblies are locked by CSharpScript's process.

[Creta5164]

hello,

I meant to report this together but didn't have time to post it separately, but I've noticed that when I start writing CSharpScript, it no longer able to compiles the project's sources and other dependent packages because the compiled assembly dlls used by the Unity project appear to be used by other processes(that's Unity editor) due to IO issues.

I'll update the issue with more details later.

Steps to reproduce

1. add the script to your Assets folder.
2. Install the external UPM package.
3. Open a notebook and run the code at least once.
4. modify the script in the Assets folder causes issue.
5. Uninstalling the external package also causes issue too.

Note These reproduction steps are based on experience and are not yet verified.
