I installed KDEnlive yesterday on W7x64 (portable stable archive kdenlive-20.08.1_standalone). It worked fine, I did some editing and did a render. Some time later I tried to render something and the render was completed after 0s and no file written - no error anywhere. So I restarted KDEnlive. But it simply crashes on startup now. I already removed both config/cache folders from appdata\roaming and appdata\local and even deleted the KDEnlive folder and extracted a new one, but it simply refuses to start. I see the splashscreen for a splitsecond, then my firewall informs me about a local connection (to dbus-daemon I assue) which I allow and then it crashes. Disabling the firewall does not do anything. Is there no way to at least get a logfile? Starting the exe via cmd won't work. Seems there is a kdenlive.exe --mlt-log debug but it does not seem to do anything? Where is the log supposed to go? When I run it via x64dbg debugger I can run until this error where it seems to crash in libmlt: SetThreadName(E440, "NVFBCAsyncThread") EXCEPTION_DEBUG_INFO: dwFirstChance: 1 ExceptionCode: 406D1388 (MS_VC_EXCEPTION) ExceptionFlags: 00000000 ExceptionAddress: 000007FEFC9BA06D kernelbase.000007FEFC9BA06D NumberParameters: 6 ExceptionInformation[00]: 0000000000001000 ExceptionInformation[01]: 000007FEDEC521E0 nvwgf2umx.000007FEDEC521E0 ExceptionInformation[02]: 00000000FFFFFFFF ExceptionInformation[03]: 0000000000000000 ExceptionInformation[04]: 000000000000054F ExceptionInformation[05]: 000007FEDE426FC2 nvwgf2umx.000007FEDE426FC2 First chance exception on 000007FEFC9BA06D (406D1388, MS_VC_EXCEPTION)!

Please do the following test. Restart the PC and start Kdenlive as administrator. Still crashing?
I restarted the PC, ran as "Administrator" account - same crash. I also updated to 20.08.2 - same.
Thanks for your report! Do you still have this problem with the latest version (at the moment 21.04, note that need to uninstall the old version completely before installing 21.04)? If it persists can you provide a backtrace (gdb command "bt full")?
