Hi,
I can just reproduce this problem in my environment as the following.
I haven’t get the exact conditions for reproduction yet, but In Studio 20.10.9 with System.Activities package 21.10.2 this occurs. If downgrade System.Activities package to 20.10.4 (this is bundled version of Studio 20.10.9) , there is no error.
So for now can you try to downgrade System.Activities package to 20.10.4, if you use Studio except the latest.
Regards,
