Omega (2210.221007-2200) has completely broken my machine and I cannot use OSU1 to recover....

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)"

https://news.xbox.com/en-us/2022/02/04/xbox-insider-release-notes-omega-2202-220202-1734/

I am currently trying Delta ring. I will report here if it helps with crashing in late game.

UPDATE:

I was able to finish the game that was constantly crashing after updating to Delta ring release Xbox Insider Release Notes - Delta (2208.220715-2200) - Xbox Wire

If Omega ring has same fixes, then hopefully everyone will get this fix soon.

I will continue testing with Delta ring with all addons enabled (currently have extra civs disabled) with new game on huge map.

But this is only one achievement from 2200 that I earned in total, and it has no criteria to earn it. THIS ACHIEVEMENT IS MISTAKE OF GFWL SERVICE. Because of it this game can't be completed.

when will xbox release a offline update for xbox insider hub

Offline system updates using OSU1 cannot be used on consoles enrolled in a Insider preview.

OSU1 can only be used on console with the General Availability OS installed.

There will never be a OSU1 file released for Insider preview OS. The console has to be removed from the Insider program before using offline system updates.

If you describe the issue you're having, with any error codes you're seeing, we will endeavour to assist you.

Lose the X completely and call it, Zbox.

If it has to be another Xbox, then call it "XBOX OMEGA".
