If that doesn't work, try resetting the Workspaces: Reset a workspace Reset the current workspace to return to its original, saved layout of panels. 1. Do one of the following: • Click the Workspace menu icon and select Reset to Saved Layout. • Choose Window > Workspace > Reset to Saved Layout. from here: https://helpx.adobe.com/premiere-pro/using/workspaces.html
If that doesn't work, try Preferences > Audio Hardware and set Input to None.
If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver)
If that doesn't work, try creating a new project and import the old one into it.
and if that doesn't work... revert to the previous version of Premiere that did work... Not a solution but a workaround.
if you find a solution, please post back and let us know.
And I'm working in the latest version without any issues... a modern NLE is a very complex beast and it's impossible for adobe to test the software on every possible permutation of hardware, OS and how the software may be interacting with other installed apps.
And it's always a good idea when posting this sort of issue to tell us your system specs: OS version, , amount of RAM, Hardware specs including graphics card. Unfortunately updates often make greater demands on your system and can sometimes no longer work.
Getting same issue. Premiere Pro doesn't even see the mp4 files from my dji device. Every other app on my Windows 11 laptop can see and play these files. I have a trial version of premiere pro. Adobe want me to pay $20-$30 per month for this. They must be have a laugh. I think I'll look for an alternative.
