I have had a similar problem a few times in VW 2022 . Objects I can move with the Toolbar Modify > Move but I cannot move it with the selection tool.
Specifically if you import this 2021 Marionette. It can be grabbed easily in 2021 and moved around but when imported into 2022 it doesn't select as an object anymore and you can't move it about.
I am sure its a newbie thing on my part.
