NRF Connect extension for SDK, "Another task is is currently building this configuration, closing"

Today for some reason after I build from Visual Studio using nrf Connect extension, the progress spinner over the configuration continues after the build completes.  When I try to build another time it immediately fails:

sign the payload
[348/350] Generating ../../zephyr/app_moved_test_update.hex
[349/350] Generating zephyr/merged.hex
[350/350] Generating zephyr/merged_domains.hex
* Terminal will be reused by tasks, press any key to close it.

* Executing task: nRF Connect: Build: app/build_shell (active)

Another task is currently building this configuration, closing.

* Terminal will be reused by tasks, press any key to close it.

If I exit and restart visual studio I am able to build once and then the problem happens again.

Any suggestions on how to fix this?
