Error Please try again later when adding ANY existing list or creating new list in ANY Teams channel

Hello,

I have multiple different lists added as tabs in different MS Teams standard channels and have had them working fine for a year. Company moved over to the new MS Teams a couple months ago and no problems.

A couple days ago I had to remove a List from a channel and now, I can't add it back. I keep getting  Error  Please try again later and the option to click a Refresh button.

I did a bunch of troubleshooting to see if it was just this list or just this channel. The most frustrating part is that it doesn't appear to just be this list or channel now. Anything I try to do with the Lists app in Teams (add exisiting list or create a new list) in any channel in any team I have I get that error. The oddest part is that I have a List in one of these channels and it's working fine but I tested to see if I can add that List to another channel in the same team or different team since it's already added and working fine in one channel, but still get the error.

Even if I try to add any exisiting list or create a new one to the channel I already have the working List in, still get the error. I've created new teams and standard channels to test this and still....the same error.

My organization uses Lists in Teams specifically to manage and track important employee information and communicate using our teams channels. I am at a loss here and can't seem to find a solution. I've done troubleshooting with Lists already and posted this on the Microsoft Lists community hub as well but wanted to post here too since it could be both or some kind of issue with MS Teams itself.

FYI - I've already done tons of troubleshooting with MS Teams the last couple days, everything you can imagine, including uninstalling, reinstalling, trying on the web, etc, etc, etc, etc.
