Lost Sequences after Adobe Premiere Pro 2025 converted a project created in Adobe Premiere Pro 2024

Hello, I just used Adobe Premiere Pro 2025 to open a project from last year which I created in Adobe Premiere Pro 2024. I converted the project as I was prompted to, but when I opened it, a whole bunch of sequences were missing in the project.

Luckily I kept 2024 installed on my laptop, otherwise I'd be screwed. When I open the project in 2024, the lost sequences are still there. In 2025, they don't exist.

I've read other users reporting the same issue on this forum and on Reddit and so on, but there isn't a fix that I can see and Adobe seems to have offered no help, support or resolution for this issue which they've brought open themselves/users in the update to 2025.

This is actually the first issue I've had with PP 2025 so far, but I am hoping Adobe/someone could perhaps point me in the direction of a solution? There isn't anything wrong with any of the footage or the project itself. It had been running just fine in PP 2024.

While I can edit away in 2024, the older version is now a bit buggy and not ideal for such a large edit. And for posterity, it would be good to know I can access this project and all its sequences in future years and not lose all this hard work due to an issue of Adobe's own making. 

Any help would be appreciated!
