What causes this issue?

You are attempting to activate Industry Extension &V1& Release &V2&. To

is compatible with the other software components, or whether add-ons
have been installed that are incompatible with the Industry extension.
As an active add-on installation queue has not yet been completely
imported, these checks cannot be made at the moment.

How to fix this error?

Complete the add-on installation in the add-on installation tool. You
can then try to activate Industry Extension &V1& Release &V2& again.
