Project does not open certain plug-ins

I have a problem in a single project, where it doesn’t activate certain plug-ins on it…
I load the plug-ins in the Insert rack, but either they can’t be opened (like Steinberg Imager, in the picture, Stereo out track) or don’t even activate (like Fabfilter plugin in the picture):

I’m running on Cubase 12.0.20, and these same plug-ins work perfectly in my other projects!

Any help?

You most likely have “Constrain delay compensation “ activated in that project
