Problem in running programs that I have downloaded and installed in OpenSuse 15.2 KDE Plasma

I have recently downloaded BitWarden (I tried AppImage, but this did not work), So I installed with Snap. This seemed to install and shows in App list but does not start. Also, I have installed OpenDrive and same problem.

Any advice or suggestiions most appreciated. I am new to Suse, so getting used to the different system.
Thanks,
Steve
