Fresh install of kdenlive Snap from Discover. Launch, after splash screen I get the following:

Could not create the video preview window.
There is something wrong with your Kdenlive install or your driver settings, please fix it.

Click OK and crashes the app.

I have the same crash. I want to add a line above the error log.
Before the lines that the original reporter pasted, I also have a 'CRITICAL' error (not sure if the original reporter had this line or not). See below.


```

Delete kdenlive-appimagerc: https://community.kde.org/Kdenlive/Configuration

Please try with the current Kdenlive AppImage version 20.08.2 to see if there are any packaging issues https://download.kde.org/stable/kdenlive/20.08/linux/ 

If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.

I was able to get around this issue by uninstalling the package and then using the PPA to install. Now everything seems to be working fine.

I still get the same crash after deleting kdenlive-appimagerc and downloading kdenlive-20.08.3-x86_64.appimage

wget https://download.kde.org/stable/kdenlive/20.08/linux/kdenlive-20.08.3-x86_64.appimage
chmod +x kdenlive-20.08.3-x86_64.appimage
rm ~/.config/kdenlive-appimagerc
./kdenlive-20.08.3-x86_64.appimage

see attached crash log

Ahh, first I didn't see that you pointed out an earlier version.

Now I tested with 20.08.2 instead of 20.08.3.

20.08.2 seems to work without crashing!
