Error: Cannot open file!

Trying to open a project in Cubase 11, doesn’t find the audio files so I click on Search, then choose the proper folder, then click Start and it finds the file, but when I click on Accept I get the window “Error: Cannot open file!”. I’ve also tried directing the files through Locate and Folder instead of Search and I get the same message. The files are fine, I can open them in Cubase 13 but not working on 11 for whatever reason.

Hi, Were the initial files from C13 ?
Just asking in case their might be a checked box in C13 while exporting and C11 maybe it didn’t support.
I know when I bounce stems for example and a collegue of mine opens them in pro tools its better to uncheck the iXML box in the export pages.
