Can't use my Adobe Photography plan anymore on my iMac

A couple of weeks ago my  Adobe Photography plan is not running the apps anymore on my iMac, no problem on my MacBook Pro.

It looks like the authentication of my account fails and I can't use PS and LR anymore.

I have followed all the trouble shooting I found in the support webpages but without success.

Tryed to cancel the certificates but no way.

I have also tryed to remove the Adobe User OS Info but the systems replies saying that the keychain is corrupted and fails to remove it.

When I try to run PS or LR I receive the message 

 Same with LR

I have tried to unistall LR/PS and also Adobe creative cloud apps but no way.

I have open a ticket to the customer support explaining in details all the facts and after few days contacted the customer service by phone to have assistance.

During the support by remote the Adobe operator tryed, along almost 2 hrs, almost what I already did...unistalling the apps, the adobe creative cloud apps, etc.

He didn't try to check the macos keychain and did a turnaround creating a new user profile in my imac.

With this turnaround everything is working but...I use my principal and unique profile to use my iMac and I don't absolutely want to reinstall all my apps in a new user profile. The gentleman at the end of his interventatio told me that is a problem that apple had to solve, I contact apple and they told me that is an Adobe problem.

I am really disappointed after several years that I am using Adobe apps to be stucked in this situation.

I am ready to migrate to alternative softwares and quit my subscription to Adobe softwares.

Hope that someone here could help me before I will take this drastic decision, 13/10/2019 is the date for the montly payment and I have already removed the Paypal automatic payment.
