September 26th Xbox Insider Release Notes – Omega Ring (1910.190923-1911)

In my understanding the Dashboard experiment, A, B, C selection, is totally random.

As "Both consoles say their OS Version is (19h1_release_xbox_dev_1911.191028-1335)" your consoles are either in the Beta or Delta ring.

Both those rings and Omega ring are getting a preview update News release notes Beta Delta Omega
Insiders today, which you can manually start or wait until it becomes mandatory.

After you do the update, if you want to change rings, it will be the perfect time to change as all those rings will be on the same release. Subject to eligibility.

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)"

Are you in the Insider program? Mixer was removed for some people in the program. https://news.xbox.com/en-us/2020/03...s-beta-delta-and-omega-ring-2004-200325-0000/

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.

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.
