I've tested this in 2.91.0 and 2.92.0 and couldn't reproduce a crash.

Please open Blender's installation directory and double click on the blender_debug_log.cmd. This will start Blender in debug mode and create log files. Try to make Blender crash again. Once it crashes the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop. Please also upload the crash log located in C:\Users\[your username]\AppData\Local\Temp\[project name].crash.txt (or simply type %TEMP% into the path bar of the Windows Explorer).

Does this only happen when using a particular music file?

No, this was actually crashing on my friend using his own music so I reproduced the issue and filed the bug. I selected a random song from my local collection. I tried another song and also had the same crash results.

I can reproduce the crash now. The crash happens because bezt is NULL in screen_ctx_selected_editable_keyframes.
