What causes this issue?

You are attempting to activate Industry Extension &V1& Release &V2&. To
allow this, the system needs to check whether the Support Package status
of the Industry extension is compatible with the other software
components, or whether add-ons have been installed that are incompatible
with the Industry extension.
As an active Support Package queue has not yet been completely imported,
these checks cannot be made at the moment.

System Response

Processing is canceled.

How to fix this error?

Finish importing the current Support Package queue in Support Package
Manager and try to activate Industry Extension &V1& Release &V2& again.
