In short : Goto Windows Security ˃ Virus & Threat Protection ˃ Ransomeware Protection (Bottom most) ˃ Manage Ransomeware protetion ˃ Allow an app through controlled folder access ˃ type 'YES' for the prompt ˃ Add an allowed app ˃ select recently blocked app (you must have tried to open Adobe PS and try to export a file) ˃ Select Adobe Photoshope and the 'Node'. When I clicked the notification which said 'Unauthorised changes blocked(Controlled access blocked)' it lead me to the ' Virus & threat Security/Protection History' in Windows Security.From there I 'allowed' the 'AdobeGCClient' or else you can simply turn of the 'controlled folder acess' under Ransome ware protection.

Me too had the same issue and tried almost everything to get rid of the warning message for which the results were negative after every attempt.But, Finally when I had an accidental glance to my notifications panel, which is at the bottom most right corner of the task bar in Win 10 I got the solution for it.
