Video playing but clips disappeared

[Julia23024744ymrh]

Hey, my video is still playing in the timeline but many of the blocks of  video and audio just aren't showing up. There's just a gap on the timeline so I can't edit this. Could someone please help? I'm trying to sort out a project for a course I'm on, which is due soon, but don't know which way to turn.

Screenshots would help to understand the issue better.

Hey as you can see here, the video is still playing but there is a gap in the timeline that I can't edit or move around:

It looks like you have additional video tracks that you have to scroll up to see it:

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.

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.
