Stuck on updating mesh colliders

[wilg]

When opening my project on another computer after making changes elsewhere, it's gotten stuck on Updating Mesh Colliders. This took over an hour before I tried this answer which pointed the finger at Gaia/GeNa: https://answers.unity.com/questions/1829430/how-to-open-project-when-stuck-on-updating-mesh-co.html

Removing the procedural worlds folder did indeed allow the project to open. However, reinstalling just caused the problem to come back.

Also, it was very frustrating that during the import process it popped up a dialog advertising this Canopy website which paused the import process. Not fun to have that interrupt a lengthy process that you don't want to baby sit.

Edit: My laptop (macOS) does not have this issue, presumably because that's where I originally made whatever changes are causing this.

I found a solution by deleting MaintenanceToken.dat as suggested below.
