there was a problem with the omega insider update

Problem seems to be with the original, and the insider omega build only.

I don't understand why everyone should not receive updates as soon as they arrive, so if problems occur, mechanisms for downgrade should be an option. Everyone on Xbox Omega Insiders should be aware of it.

As I mentioned, if it's not among the ones listed, you should use OSU1

Except that the OP is running an Insiders build (the OS build information is the latest Insiders update) so your advice will likely lead to a broken console!

What the OP posted is a match to the lastest Omega ring update (also seems to match all the updates from all the rings) from 4th February, unless I am missing something:

"Xbox Insider Release Notes – Omega (2202.220202-1734)"

Okay, can you share the feedback link here, please? I’ll ask the team about it.

The Insider update should’ve improved the performance, so it’s strange that it hasn’t made any difference. If you joined the Omega preview, this is the most recent update (it’s possible that it installed automatically by itself if the option to keep your console up to date is enabled):

Here to help.

Instead of leaving the Xbox Insider program as one Ambassador has suggested you can drop down to a lower ring which receives much fewer updates. For example if you are in Beta ring drop down to Delta or Omega. The Omega ring receives the fewest updates,
usually just before it is released to the general public. This can be managed using the Xbox Insider Hub on your console.
