Hi @SY_MSO ,
To verify your issue, what's the type of the account?

But Outlook desktop app does not open on any computer .

Have you tried opening other profiles? does the problem occur to the specific account or all accounts?
Given that troubleshotting you have done, it is recommended that you try the following workaround:

• Run Outlook in safe mode, check if the issue is related to the third-party add-ins.
  To run in safe mode, type outlook.exe /safe in command.
  If Outlook works fine in the safe mode, then you’ll have to disable the add-ins, here is an article for your reference
• Type outlook.exe /resetnavpane in command to see if the issue persists.
