For users affected by the Adobe deactivation and have a Pro license, please follow the steps below.
Signing out and signing back in usually resolves this issue.
Launch Acrobat Pro or the Creative Cloud desktop app. Click the profile icon in the upper-right corner of the app and click Sign Out.
You can also do it from the Acrobat Pro toolbar:
Completely close out of the Adobe app
Re-open the Adobe app (ex: Acrobat Pro or Photoshop)
Sign back in with the account associated with your subscription (usually your SU credentials and the company/school option).
