"Matrix Cannot Be Inverted" Error After Converting CS6 Projects to Premiere Pro 2024

[Andre0D4C]

I have a lot of CS6 projects that I'm going back and reworking in Premiere Pro 2024. This worked fine for a while, but starting a couple of months ago an annoying glitch popped up.

When I specifiy the destination folder and tell it to create the new version of the project, it does its thing, pops up the warning about the Legacy Titler no longer being supported, and creates the project. However, when it does so, the Project window - the one that lets me see and organize all the sequences, bins and media in the project(!) - is missing from its usual place in my workspace.

If I go to the Windows menu, Projects> and select the project name, an error pops up that says "Matrix Cannot Be Inverted."

So in order to work around this, I have to start a brand new PP 24 project, then import the main sequence and its accompanying media from the CS6 project. This works, but seems unnecessarily kludgy and time-consuming especiall for something that used to work fine.

I've recently started evaluating old projects also. (circa 2014) I am encountering the same error under the same circumstances. Thanks for the workaround. At least I know the project isn't gone forever.

Update: Today, for the first time in 6 months; I had an old CS6 project *not* go stupid on me in this manner when opened/resaved in Premiere Pro 24. I was actually able to pull up my sequences, tweak them and re-export the final product without having to take that extra step of first creating a new version of the project and importing the sequences into it. I didn't change anything on my end; I wonder if Adobe updated something under the hood or a recent Windows update perhaps could have unknowingly solved the issue?

Update: As of April 2024, the issue has mysteriously returned. Upon opening an old CS6 project within Premiere Pro 2025, the Project window with all of my sequences and media vanishes and a "Matrix cannot be inverted" error pops up. I now have to go back to creating a new project and importing the sequences from the old project into it.

This has also returned for me on May 2nd, mysteriously appearing after working on a new project. This error should be an internal Premiere Pro error, this is appears to be a nonuseful error message for editors to see, and it isn't descriptive to what the problem may be. Can Adobe devs fix this?

Having the same problem after the 2025 update. Very frustrating. I in an earlier thread about this from years past, Adobe said it was a bug and would have an update for it. So, hey Adobe, is there an update to fix this coming soon?!

Is there a fix to this or do we just keep paying the expensive Adobe subscriptions and accept all these bugs and glitches?
