Hello, RoValf.
Welcome to Microsoft Community!
If you find that this occurs after a firmware update, I am sharing with you a link to the tool for hiding the latest firmware update here, where you can choose to hide the most recent one:
http://download.microsoft.com/download/F/2/2/F22D5FDB-59CD-4275-8C95-1BE17BF70B21/wushowhide.diagcab
(If the download bar in the top right of Edge suggests that the content is blocked, click on the keep option of the three dots to the right of the file)
If the issue no longer recurs after hiding the update, we will record the firmware update version numbers and submit feedback subsequently.
I also recommend downloading drivers and firmware for the Surface Thunderbolt 4 to troubleshoot potential compatibility issues:
Download Surface Thunderbolt 4 Dock Firmware and Drivers from Official Microsoft Download Center
Here are some things we can try at the moment.
Any progress is worth sharing, which also helps us determine whether the issue could arise from hardware.
I am here to support you.
Best Regards.

Hi Leo,
unfortunately your Tool doesn't detect any Update (Hidden or Not) as also reported by John.
About the Surface Thunderbolt 4 Dock Firmware and Drivers, I usually update firmware and drivers once published. Then I've installed the latest.
As suggested by John, waiting your fix, can you give us the link for download the previous version of these two firmware files?
With the previuos version all was running fine.
Please, it's frustrating and impossible to work on this situation!
