glitch during transition

I've tried everything and nothing helped. I did render an older project and it went through with no issues which makes me feel like its something with my one clips. So i systematically started removing and exporting the video and i'm still glitching. i have no clue what to do.

 Hi nikki31933954nw0e!

Sorry about the trouble. What's the source of media files? Could you share your system details (OS, CPU, RAM, GPU)?

Do you have any updates available for your GPU driver?

Let us know.

Thanks,

Kartika

Does it happen if you export directly from Premiere Pro?

Does it work OK if you turn off Hardware Encoding in the export settings?

Delete the Media Cache and Media Cache files:

If that doesn't work, try resetting the preferences:

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:

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.
