Uninstalled and reinstalled QGIS but plugins get reloaded. And crashes when initiated. How do we go about reinstalling with a clean profile with no plugins installed? After uninstalling QGIS I have deleted all registry entries and folders related to QGIS. Yet the previously installed plugins (the problematic ones too) get reloaded.

Would appreciate a quick response.

Would like to add that I am unable to uninstall the "semi automatic classification" plugin as the program crashes every time I try it.

QGIS 3 stores all settings, plugins etc in a directory you can access by menu Settings -> User Profiles -> Open Active Profile Folder.

So first please remove the plugin by removing the python\plugins\SemiAutomaticClassificationPlugin subdirectory from there.

If if doesn't help, please create a clean profile like Nyall said: menu Settings -> User Profiles -> New Profile (alternatively, you can just remove everything from the default profile directory, if you don't have any valuable settings there). It should fix most issues, as even all the settings placed previously (QGIS 2) in the Windows Registry are in this directory now.

Thanks Borys and Nyall for your inputs. I removed the last four installed plugins from the Python folder, including Semi Automatic Classification and the problem has been resolved. Cheers!!
