Hello KDE-community!

I'm new both here and to Kdenlive (and well aware of my noob status), so please bear with me

Here's the issue: Kdenlive got suddenly stuck while I was finishing a project, to the degree that I couldn't do anything else on my PC for several minutes and had to restart it. When I visit the project folder now, there's not just my original .kdenlive file, but also an additional one with "-2400" at the end. Neither of them can be opened and get stuck on 'loading'.

Is there a way to uncorrupt the files? (Other projects open normally.)

System: Windows 10
Kdenlive: 20.24.0, MLT version 6.21.0, FFmpeg libraries
