I can’t load package manager as I have many issues

• Certificate generation getting 404 from server right after login with Samsung account
• I can’t able to add a new DUID into existing cert

 When I tried to run package manager through CLI I can see following message then nothing 

2021-01-29 16:25:46.928 java[17822:281294] *** WARNING: Method userSpaceScaleFactor in class NSWindow is deprecated on 10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead.

 Can you help me to get out of this please?
