System Information
Operating system: Windows 10

Blender Version
Working:

2.81a regular release (NVIDIA Quadro P5000 desktop)

Broken:

2.83.2 regular release (NVIDIA Quadro P5000 desktop)
2.83.1 regular release (NVIDIA Quadro P5000 laptop)

Short description of error
Blender crashes (closes suddenly) if a strip currently being cached is deleted before the cache/prefetch process is allowed to complete.

Exact steps for others to reproduce the error

Load new blender file. Choose "Video Editing" for convenience.
Insert a movie (with or without an audio channel) into the VSE
- You may wish to give yourself time to delete the strips before caching completes; increase the scene end frame, increase the sequencer cache limit.
In the preview-type video sequencer viewport, properties panel, select (enable) prefetch frames. You can observe the red cache status bar in the sequencer working properly.

Before the caching stops (either from memory allocation full or all frames cached) delete the strips. If the movie has an audio channel you will need to delete both the audio and video strips.

[VSE] Crash if strip is deleted before frame prefetch cache completes #79064

Before the caching stops (either from memory allocation full or all frames cached) delete the strips. If the movie has an audio channel you will need to delete both the audio and video strips.
