Error on Photoshop launch from Shotgun

When launching Photoshop from Shotgun Create it gives an “integration error.” It will launch other applications.
Shotgun Integration Error
executing remote command
<ExternalCommand Photoshop CC2021
@ tk-shotgun Task 6645>.

Hey I’m just moving this over to the Create category, so it gets visibility there.

It is not just a Shotgun create issue, that is why I posted to Integration. Just the one that will provide an error.
When using Desktop, it will not launch Photoshop at all.
When directly launching Photoshop, it sits on “Loading Shotgun Integration” and goes no further with that function.
I can provide the full error provided if needed.
