"Media offline" in multicam project after upgrade to Premiere Pro v25.0.0

What happens when you right click on your media files and select relink?

@jamieclarke, 

I did it the way you recommended (Shift during starting Premiere Pro)-1-, via "Voreinstellungen (english: Presettings) | Media-Cache | 'remove unused files from media-cache'-2- and 'remove all media-cache (restart requered)'-3-" and via script ("del /q %SYSTEMDRIVE%"\Users\"%USERNAME%"\AppData\Roaming\Adobe\Common\Media Cache Files\*")-4-.

In case of 1 and 3, after reopeneing the project-file (*.prproj), Premiere Pro created new peak-files for the *.wav- and for the *.mp4-files, but not for the *.m2ts-files. 
The initial issue remains unchanged: The *.mp4-footage is shown. The *.m2ts-footage shows "Media offline" as can be seen in the initial screenshots. 
Regards, Andreas

Hi @Andreas23802052vbg1 - When you upgraded to version 25 did you try clearing the media cache?  You can hold down "Shift" while opening premiere and select the checkbox "clear media cache files".

Once you reconnect your media files do they stay connected or go offline again?

This is the 3rd attempt to answer Kevins post (answers disappeared from thread after posting?): 
There is no network drive at all. Everything (Premiere project files [*.prproj], footage and the Premiere app installation itself) is stored on a Western Digital Blue SN570 2 TByte NVMe SSD. 

Regards, hope you can help soon, Andreas

Same applies to 2 other multicam-projects, check screenshots.
