"Matrix Cannot be Inverted" Error

I'm having the same issue.

Importing the old project from 2019 into a new project seemed to fix it. However, after saving the project and closing Premiere Pro for the day, I found that reopening the project a different day brought the error back. 

Use the template below to provide us with information: 

• Issue – I receive a Matrix cannot be Inverted error in a box on the lower right. I cannot open the Projects panel. When I go to Windows-Projects I get the error. When I try again, I can see a selection of the project. When I try again, I can see two selections of the project. In other words, every time I try, it seems to add a new "version" of the project to the Windows-Projects window, but none of them will work.
• Steps to reproduce – Open an older project in Premiere Pro and the error will probably occur. If not, go to Windows-Projects.
• Expected result – I should be able to see the Projects tab and work on all the associated files with the project.
• Actual result – I get the Matrix Cannot be Inverted Error and the Projects tab never opens. A project name is added to the Windows-Projects menu option every time I try to open the Projects tab, although it is the same name over and over.
• Screen recording – If you think it might be helpful, include a recording of your screen, showing the issue.  
• Adobe Premiere Pro version – 25.2.3 Build 4
• Operating system – Windows 10
• GPU driver version (Windows only) – NVIDIA GeForce RTX 2070 SUPER Driver Version 32.0.15.7680 6/12/2025
