Audition 26.0.0.56 Won't open 25.3.0.71 Sessions

Returned to work from vacation to find Audition had updated itself while I was away. New version is 26.0.0.56 Build. When I try to open sessions I produced in Audition 25.3.0.71, Audition comes up with the Can’t find all Media pop-up and wants me to link to the Media. When I try to link media (even if I manually try to link the media by right-clicking on the clip and selecting Link Media, it doesn’t work. I cannot seem to open old sessions with the new 2026 version.

In my workplace, (radio station) I have to save all sessions to a OneDrive, accessible to all producers across the country, so anyone can work on anything. I have not tried to open an old session from my local HDD. (yet) I have reverted back to Audition 2025 so I can complete my work. Audition 2025 still opens everything normally… even from the Company OneDrive.
