Compiling takes incrementally longer each time

Hi all, I'm in Unity 2020.2.1f1

Our team has noticed that each time the code recompiles: unity takes longer and longer to come out of it. The only thing we're able to do to alleviate it is to exit, and restart unity.

It gets stuck on "Reload Script Assemblies" and will get to over a minute before we finally break down and restart.

Does anyone know how to fix this?

It seems to be affecting exponentially worse if you have plug-ins... any dlls. If you have a project with none: this doesn't become an issue. So why is it that this is happening? Surely we're not the only ones.
