catalina – accountsd process uses all CPU – AMSAccountStoreCache error

the process accountsd is using more than 300 % of my CPU. The error messages in the console that appear are:

  • AMSAccountStoreCache: [AF547297] An ACAccountStore has no associated media type. Returning the default media type for the current process. accountStore = AMSAccountStoreCache | defaultMediaType =
  • "Cannot check access to a private account type:"

What I already tried from other questions:

  • Remove Mail accounts
  • Remove calendar accounts
  • Stop Spotlight from indexing your HDD
  • Kill AppleSpell and delete Spelling folder

Still the same error. Any ideas? Thanks!
