Over-wrote original file when exporting (did not get a warning) 23.6.0 Beta (build 48) Mac OS 14.4.1

Over-wrote original file when exporting (did not get a warning) 23.6.0 Beta (build 48) Mac OS 14.4.1 M2 MAC Studio Ulta 128GB Ram

Here was the process:

Marked in and out points on the source clip.

Dragged to the timeline to create a matching sequence (which named the sequence after the clip ...as expected)

(A sequence had not been created yet - so it was the blank region.)

Added clips and filters to the sequence

Exported using the quick export function, which I customized under more presets to QuickTime ProResHQ

Selected the same folder as the source media as I planned to bring this clip back into the project.

And hit export.

(Granted this is not a proper editing procedure as I should have renamed the exported file and put it in a new folder of modified media.  But I was just running testing out the new beta release.)

After the export, a series of errors popped up about corrupted frames. 

All media disappeared from my Project panel and the clips though still in the timeline did not play back.

I discovered that the exported clip overwrote the master with the same name.

Since this was all just for testing - I used a copy of the media and nothing was truly lost.  

But for a new user who may actually lose their original media by not paying attention, this could be a YIKES situation.

BTW - Love the new updates and additions and realize these are the kind of bugs you can get working with a beta release.
