Application Talk user last meetings greyd out

Hello I have a problem with one of users using application Talk. After one of upgrades between 18 to 19 version one of users has its last talks greyd out (see the attached picture). if You add a talk it is visible until user logs out but afterwards it greyd out again. Is this a permission issue?
Current version of nextcloud I have is 19 and Talk version is 9.0.5.

Any help would be appreciated?

No, there is an issue with the servers response on getting the room list.
Can you press F12 and switch to the console tab in the browser tools that opened to see if there is a red error line?

Lots of errors like: JQMIGRATE: Migrate is installed, version 1.4.1
globals.js:61 $ is deprecated: The global jQuery is deprecated. It will be updated to v2.4 in Nextcloud 20 and v3.x in Nextcloud 21. In later versions of Nextcloud it might be removed completely. Please ship your own.
