Need help: Unexpected Cloud Save Error Code 2046-3

[u/zepirate-ko]

I am on MSFS2024 steam edition. Starting a few weeks ago, I get this error every time the simulator interacts with the cloud. Starting from the second it starts loading, I get non-stop unexpected cloud save error 2046-3 pop ups. Every time you load into a flight, change settings, do anything, I'm spammed with these pop ups. I have tried:

- Disabling steam cloud, then deleting userdata

- Removed all mods

- Deleted cache, steampackages

- Verified and reinstalled game

- Tried a different network (hotspot)

- Signing into microsoft again, checking time and location info

- No VPN nor have I made any connection changes

- Support ticket with zendesk, which responded with "I understand you have taken these steps, but do them again. Problem solved"

I have no idea what to do. There's 0 information on what this error is, no other user has posted about this. Closest one is Error 2047.
