Cannot use video tranistions at all.

I am using the 2025 update 

windows 11 home

As of today I can no longer drag and drop any video transitions.  When grab them and drag them over the interface between clips, the pointer just stays an arrow. it doesn't even act like I am trying to insert a transition at all. The layer is activated. I'm not getting any error about handles or anything else at all. just doesn't do anything.

When I try to apply audio transitions it works as expected. 

I tried to set a video transition as a default transition, highlight the two clips, and hit ctrl D, and this does nothing as well. 

I have uninstalled premier pro and reinstalled and it still has this problem. it's live video transitions don't exist at all. 

it worked fine yesterday and I don't think I have changed any settings since then.
