red .r3d files not importing to Premiere Pro 25.1

[ryanp16926081]

Have had no problems importing and running .r3d files in Premiere Pro up until now. Suspect related to upgrade to v25.1. 

Mac M1 2020

Premiere Pro 25.1

Both on existing projects that were created and ran fine under all pre-25.1 versions, and on attempt to import into new projectsl using standard protocol through Media Browser, I navigate to r3d files, or folders in which they are contained, and failure message:

"File format not supported." 

Cannot figure out why.

Under Media Browser>Directory Viewes "RED" is checked and highlighted.

I re-downloaded both RED Cine-x pro and Red Apple workflow installer. still negative function. 

Any advice?

Try starting up Premiere Pro while pressing the Shift key. Choose to delete all the media cache from the Reset Options dialgo box. See if that helps, @ryanp16926081.

When starting up Premier Pro while pressing (holding down continuously) Shift key, and dialog box appears "Skip loading optional and third party plugins?" Regardless of selecting NO or YES, Premiere otherwise starts up as normal. There is no "Reset Options" dialog box. Any further advice? Do I need to dig into the media cache menu to delete?

Turns out the command to bring up RESET OPTIOMS dialog is Shift+Option. Clearing the media cache worked! Thank you.

Awesome. Any key should work, though. Sorry for the hassle!
