Kdenlive keeps randomly crashing and bugging and I’m losing my progress! How to stop it?
Without more details like Kdenlive version, platform (Windows, Linux, macOS), circumsatnces when it crashes (what you are doing, resources you are using), it is going to be impossible to help you.
When you are on Linux then open a terminal and type:
kdenlive
There will probably be texts and when the program crashes most likely an error.
Just do in Kdenlive what you normally do. After the crash select all lines in the terminal, right-click on the selection and choose copy.
Then here in your answer click the </> button on the top of this window, right-click on the text: type or paste code here and chose paste.
Most likely there will be some hint about the cause.
