Link Unfurling stopped working in latest version of new Teams

[Naina-G]

Steps to reproduce

We have a working integration scenario where we share can share a link to Teams which unfurls to show an adaptive card. This adaptive card also has the refresh clause to bring up more detailed card for authorised users.
However we updated our Microsoft Teams version recently and with latest version of new Teams we can see that this existing flow has broken and whenever we paste a valid link to Teams, it is not unfurling and we get an error message "Oops, something happened with the editor".

As of last week, we could see this error only in Teams web version, however now this issue is reproducible across web, Desktop (Windows and Mac).

Version details for Teams Application

Note: This breaks our existing production flows as well please suggest if there is any other channel to get a quicker resolution on this

Expected behavior

When a valid link is pasted in teams it should unfurl and bring a proper adaptive card.

Actual behavior

Pasting a valid link is not unfurling to an adaptive card instead its bringing the below error.

We tried to setup this sample https://github.com/OfficeDev/Microsoft-Teams-Samples/tree/main/samples/msgext-link-unfurling. We are getting the above error while adding the app itself.

@Meghana-MSFT Thanks for confirming that you are able to see the error as well.
Is there a reason why this is happening in new Teams latest version.
Could you share a solution for this?
