I am unable to delete or create new projects (pls help)

I keep getting errors, preventing the creation and deletion of core projects. pls help. My existing project repeatedly shows errors from the autosave.

pls help

Where you installed Core? / in the Web or on Epicgames launcher?
If its on the Epicgames laucnher you youst can Check the application.
When you installed it in the Web i would try to Save my Actuall games(when you allready published it you dont can updtate it you only can publish it new) and then reinstall Core.
Good day,

(If you have other Questions pls response. If it helped, it help me when you give the Comment a upvoat and solution)
