FYI: I just updated one of our "Remote PC Access" Fat Clients from VDA 2402 to 2411 and immediately had two issues: 1. Windows Hello for Business PIN stopped working. 2. MS Teams v2 is in an endless crash loop. Both issues vanish, as soon as I downgrade to VDA 2402.

regarding your second point: https://www.reddit.com/r/Citrix/comments/1hc1vve/vda_2411_and_teams_2_continually_restarting/

Mh, so maybe a known issue with the VDA. Sad.
