I’ve done the usual - moved\renamed my old LOCALAPPDATA\darktable -
darkatable just runs as a headless process - darktable.exe is running - visible in the process list, but no application window UNTIL I kill the gdbus.exe process at which point DT finally opens minus a couple of right hand module tabs. The Opencl stuff appears all present and correct in the settings.
Ive tried --disable-opencl etc
Any suggestions?
Why is gdbus running in the first place?
Darktable starts it and from what I’ve read it has something to do with Lua scripts. When its killed DT opens with missing module tabs.
Start darktable from the terminal: darktable.exe -d common and share the log file.
Was wondering how to attach the log when I first posted! Now I see an option in the reply box I should have replied to myself! 
Anyway here it is - well 2 launches no error messages. However before this I tried the latest beta and it complained it was not able to open library.db and data.db read/write so Im wondering if its a sqllite problem. Anyway I emptied out the local darktable profile so the small log is for a fresh launch. The zipped one is the log from the last few days of trying to debug.
