Hey, I've been using Premier Pro for a about 2 years now and this is the first it's ever done this. About a week ago I edited a video and it worked perfectly, but a few days later I opened the program and it was extremely lagging and anywhere from 3- 5 minutes it just closes the program with no error code. I've tried uninstalling and reinstalling, checking for updates, removing excess files from the computer; nothing is working to fix it. The computer I have is HP Spectre, Inter Core i7, 16Gb RAM
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.
