Connectivity Kit version 20210609 non responsive

[StephanP]

Discovery:

- So, the latest CK (v20210609) installed on a fresh new W10 (Education) tends to choke, become non-responsive.
- After uninstalling this version 2021 and replacing this with the previous version (2018), it turns out that that version just works fine.
- Soon enough, CK 2018 suggested an update to version 2021, which I allowed to proceed.
- After this update CK version 20210609 works.

So, yes. Apparently some dependency was missing.
