Bug Compilation when adding or removing a package takes 30 minutes or more.

After upgrading our project to unity 2019 LTS from 2018LTS compilation takes FOREVER.

Each individual assembly takes several minutes and it does this repeatedly.

Code (CSharp):

1.  
2. System.Threading.ExecutionContext:RunInternal(ExecutionContext, ContextCallback, Object, Boolean)
3. System.Threading.ExecutionContext:Run(ExecutionContext, ContextCallback, Object, Boolean)
4. System.Threading.ExecutionContext:Run(ExecutionContext, ContextCallback, Object)
5. System.Threading.ThreadHelper:ThreadStart()

You can see the compile times are ridiculous, none of my other projects act like this. What do I do?

Also my CPU is not slow, and deleting the library folder did not solve this issue. I use similar assets across my other projects and none of them act like this, and the project did not act like this before switching to unity 2019.

 

Hey there!

Can you submit a bug report (https://unity3d.com/unity/qa/bug-reporting) and submit your project so we can diagnose it?

Thank you!

 

It seems the issue was related to an old version of VRTK4.

Removing it solved this issue, but it is bizarre that this can happen.
