"Why no delta updates"

Sounds like your console is enrolled in the Delta Xbox Insiders preview. If so, you should check the Xbox Insider Forum on Reddit.

The reason you may be getting large 2GB updates is you missed a preview update and the console will download the complete updated OS specific to the Delta preview.

If your only internet access is a phone hotspot I suggest you unenroll from all Insider previews and return the console to the General release OS for xbox consoles.

For example, my console is enrolled in the Alpha skip ahead preview and I do 3-4 updates to the OS a week. It doesn't take long to use 2GB a week just in OS 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.

Hey, Delta. The Blu-ray app update is not a preview version. It is an update that was released to the general public. To enable 3D Blu-ray playback, you need this app update combined with the system update that is currently in Preview.

Major Nelson listed all the formats available in his blog post about this. WAV is listed.
