I have the same issue. Preferences were reset.
It only happens when the Develop module opens. I have Photoshop CC installed as well and this is the first time I have tried opening Lightroom since the last Photoshop update.
I also have same issues. When I use the Develop module, LR is closed.
Does anyone know hot to fix it?
Found the cause of my problem.
Nvidia Drivers version 381.65 are not compatible.
went back to 378.92 and all is working again.
Sadly not, though it did ask to reset the preferences, then fell over.
I'm using onboard graphics, so not my problem, glad yours is working though.
I'm not sure what you mean about 'when the develop module opens' Sounds like a different problem.
I've found the error logfile for mine; here's the end of it:
LoadedModule=C:\Program Files\Adobe\Adobe Lightroom\video_toolkit.dll
LoadedModule=C:\Program Files\Adobe\Adobe Lightroom\catalog_converters.dll
LoadedModule=C:\Program Files\Adobe\Adobe Lightroom\Import.lrmodule
AppName=Adobe Photoshop Lightroom
AppPath=C:\Program Files\Adobe\Adobe Lightroom\lightroom.exe
I like the 'friendly event name'!
Update, I've tried renaming the catalog file. Lightroom notices that it isn't there, so I tell it to use a default one, then it falls over, same fault in the log
New version of Lightroom available today. Sadly hasn't fixed the problem.
Solved. Following 3 hours of effort from Adobe support, we found a problem with AppData\Local\Lightroom. Deleted that, it all took off.
Hat bei mir leider nicht funktioniert
Did not work for me
