Problem with Delta Ring updates

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.

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.

Seems you have to be invited to join the Alpha ring

The current Xbox One Update Preview rings are:

• Alpha – Open on an “invite only” basis and receives updates at the earliest point in the preview window.
• Beta – Open to Xbox Insiders with a Program tenure of 3 or more months and an Xbox Insider XP Level of 5 or higher. This ring receives updates shortly after Alpha.
• Delta – Open to any Xbox Insider with a tenure of 1 or more months that has reached Xbox Insider Level 2 or higher. Depending on certain edge cases where further attention is required from Alpha or Beta rings, Delta Insiders may receive
  system updates before Beta, though this is not a common scenario. Additionally, while early system updates are not guaranteed across the Delta ring, all Delta Insiders will receive the update prior to GA.
• Omega – Open to anyone and receives system updates shortly before the GA (General Availability) release.

You just have to continue to be active in the program, take part in surveys, etc. but Alpha is also by invite only so you would have to wait to be invited into it by Microsoft.

How do the Xbox One Update Preview rings differ and how do I change rings?

There are four Xbox One Update Preview rings, which allow you control when and how often you will get early access to console updates. You’ll gain access to rings based on your activity as an Xbox Insider. If you’ve been invited to more than one ring, you
can switch between them from the Xbox Insider Hub.

• Omega – Open to anyone and receives system updates shortly before the GA (General Availability) release.

I really wouldn't like to say yes to that as the Omega ring gets updates just before general release so the odds aren't good.
