Reimport problem when switching between versions

Unity Engine
1

Hello.

When switching between projects I encounter a strange problem. I have a 2019.3 project and a 2018.1 project. When I open the 2018.1 project, everything is fine. When I close and switch back to my 2019.3 project, Unity shows an Import window and it keeps showing com.unity.terrain-tools\Shaders(a ton of folders and files) and it does this for upwards of 15min. If my project ever finishes loading, I’m going to remove the terrain tools because this is this 3rd time this has happened. Anyone else encounter something like this? Not sure if this is an error or something I’m causing. I haven’t done anything with the terrain tools in this project so not sure what the problem is.

Do you open the same project folder with different unity versions or is it different project folders?

It’s different projects. I use VRM models in my project and for some reason I can’t import them with 2019 without first importing into 2018.1.

The 2018 project only has the VRM importer. I removed terrain tools from my project but it still does this. It will show an Import dialog box and I have to switch to a different version, quit out, and switch back to 2019.3 in order to open the project at all when this error happens. Am I the only one?
