Video Transition missing Error (no third party transitons)

[Rodrigo Suarez]

Hi everyone, 

I am getting this error when I open all my projects that have transitions.

These are the only transitions I use (no third-party transitions). 

I can still see the transition on the project timeline, even though it's not reproduced on preview or when the project is exported.  

- Windows 11

- Premiere Pro v24.1

When I first place the transition, everything works fine. After saving and reopening the project, the error comes up and I have to delete and place all transitions again. 

If I place the transitions and export the project without closing the project, the exported file will reproduce the transitions perfectly. 

Would be thankful for any help on how to fix this problem/bug.

Delete the Media Cache and Media Cache files:

If that doesn't work, try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.

I tried all 6 suggestions and nothing worked. Honestly, feels like generic solutions for when a bug/problem can't be identified.

If you zoom in on the transition you will see which one is used.

Sorry, I don't understand how this will solve the problem, but here's a print screen of a zoomed-in transition.

You will need to replace them manually.

I do, but when I save and open the project again, the same thing happens.

Same exact thing happens to me but I use a MAC. I yet to find a solution.
