delta ring previewer here with a bone to pick.

Hi Volcannon,

Yes, you can rejoin after leaving at any point. It's possible that by joining and gaining exp so that you move up the preview rings to Delta at least so that you may get a future preview update where this issue is addressed and you can test it out for yourself
before those in the Omega ring or not in the preview program. Beta ring previews updates before Delta ring and the Alpha ring, where updates are tested first, requires an invitation to join.

Either way a solution to this will more than likely be tested in the preview program first. News regarding what is included in recent preview updates for the different ring levels can be found here:

Also here is an FAQ all about the Xbox Insider Program:

To change your preview ring go intk the app then insider content. Scroll to the far right and click on build tab then click on the preview ring and it should appear as a drop down to change to delta or lower. Then reset. And to change back to alpha just
repeat the process once fixes are in place.

For alpha preview yes they come in waves, because is a lot of players want to trying alpha ring...

If you dont want to wait, always have Delta or Beta Ring. On both of that you get accepted with no time of wait.

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.
