EuCon 2021_10_0_96 - Assignable Knob does not work

After installing the latest EuCon version 2021_10_0_96 the “Assignable Knob” does not work on any of the Artist series controllers (MC Transport, MC Control). Can someone please confirm this problem? On the previous version 2021_6_1_7 Assignable Knob works without problems.
