All my clips (hundreds) are offline.

Have been using Premiere Pro 2025, the app updated itself to the latest version (26) and is saying all my clips (hundreds) are offiline. When I try to relink them it says there is an issue with the audio channels type. Its ridiculous because I've been working on this project for months and have never had this issue. I re dowloaded the older version of PP and now thats doing the same thing...  not sure if this is a bug or somethng Ive done
