Remove this file:
C/users/username/appdata/raoming/Adobe/premiere pro/version number/Effect Presets and Custom items.prfpset
Then open your project. You will have lost all your presets.
Then make a new project and open the old one in this new one.
Thank you very, very much!!!!!!!!!!!! Solved!!!!!!!!
I had same problem. Then i called Adobe help. Someone then took over my pc and checked the windows error log. He conluded that the error was located in a dll file, due to a C++ update. His remedy was then to have me reinstall my entire OS from scratch... ;-(
During his actions he removed the appdata/adobe/prefs file, but in my case it is located on another drive. After I deleted the prefs file from there all was fine again. Except workspaces etc were gone. But they can be imported with older pojects?
But, as soon as I sync/downloaded the settings, again the same cloudroom error.
So deducing all in all, I suspect something went awry with the last update?
