Trados studio stopped working right after installing Cumulative Update 7 (Build 17.1.7.17560) - Object reference not set to an instance of an object

Arya. H

Hi, 

I recently installed Cumulative Update 7 for Trados Studio 2022 SR1 (Build 17.1.7.17560).
Before this, I was using the latest version, which was Cumulative Update 6 Trados Studio 2022 SR1.
However, I am now encountering this infamous error message that appears as soon as I open Studio:
Object reference not set to an instance of an object

After clicking OK, Trados Studio shuts down completely

Attached are the XML file (error details).

I would greatly appreciate any suggestions you may have to solve this issue.

    I tried all suggestions provided by  and . Additionally, I disabled Onedrive and my Antivirus software entirely.
    Yet, the same error pops up after launching Trados, and then Trados fails to load after hitting the "OK" button.
    It seems like there might be a more serious issue with this update.
    Tagging        for awareness.
    Is there an updated guide (for 2023) on downgrading Trados safely without losing cloud and local projects?
    I have attached my latest stack trace below:
