In the second warning popup dialog (too many warning popup dialogs!), click Continue.

Thanks for your report! I recently made some fixes to the cache management. Can you please try if this is still happening with the 21.04 release candidate: https://files.kde.org/kdenlive/unstable/kdenlive-21.04.0-rc-x86_64.appimage Btw I don't know if you are aware of how to use gdb correctly (I wasn't for a long time so I am going to explain)… After you did $ gdb ./kdenlive-20.12.3a-x86_64.appimage you will see something like Reading symbols from /home/user/kdenlive-20.12.3a-x86_64.appimage... (No debugging symbols found in /home/user/kdenlive-20.12.3a-x86_64.appimage) (gdb) then you have to enter "r" and hit enter. After kdenlive crashed you have to type "bt full" and hit enter to see the stack
Hey Yes I am familiar with gdb, but the stack is empty, so no backtrace. I tested kdenlive-21.04.0-rc-x86_64.appimage and received the same 2 confirmation popups and reproduced the same crash. (gdb) bt full No stack.
It seems you have opened "Manage Cached Data" after you opened a project or changed anything on the "untitled" project (i.e. you see two tabs "Current Project" and "All Projects"), right? …and you haven't selected any "auto-generated numeric name" but the one of the current project. That's also the reason why you get multiple popup dialogs… Unfortunately I can still not reproduce, for me it works fine. What is your OS?
> It seems you have opened "Manage Cached Data" after you opened a project or changed anything on the "untitled" project Negative, the steps to reproduce are from once I start kdenlive. I'm using Sabayon. I will attach a screencast to help.
Created attachment 137758 [details] Screencast of crash
Thank you for the screen record. That was very useful, I was able to reproduce now! It seems to happen only if you are on a empty project and select the first auto-generated numeric name entry. It happens even with the flapak and was able to get a backtrace there. However it does not happen with builds from master / nightly build. That's likely because I made further changes in the master branch that are not going to be in 21.04. I have to check if I can port them for 21.04.1 otherwise they will be in 21.08 If you can confirm that it is fixed with the nightly that would be nice: https://binary-factory.kde.org/job/Kdenlive_Nightly_Appimage_Build/

Please test with the nightly build as asked above.

Tested kdenlive-21.07.70-9b89f4e-x86_64.appimage with no project open. Crash fixed. There are still 2 popups with the same message. If I select all folders and click "Clear current cache", OR if I delete all folders one by one and then delete the last one, the last one appears twice.

Yes I can confirmed the duplicated entry with today's git master
