Plugins stop working

This has happened a few times. After working on a project, with a number of plugins on inserts, everything is working fine.
The next day when opening up the project all plugins are greyed out and cant be opened.
Changing audio interface does not make any difference.
The only thing that works is to create a whole new project and inport the tracks (but without any inserts) and redo all the plugins. Using VST plugins.
Running on a PC, Windows 10, 64GB of Ram.

Constrain delay compensation?
