Cant copy past from model to model in 2023 pro

For some reason, I can’t copy and paste things from file to file in 2023.
I can copy and paste in the model itself, but if I want to copy something from one model, and then paste it in another model, like I’ve done many times before, I now can no longer do it.
And yes, everything is in the same version of Skp.
Any thoughts?

Multiple threads on this topic already. The developers are working on a solution. A work around was given two weeks ago. See:

Like I said. Same version

Like I said, the developers are aware of this and a work around has been provided for the time being.
