Notes (Required)

I tested for over 5 hours in multiple new worlds with the mod installed using the /locate command to look for the Labyrinth and none spawn, same with the invoker mob in the woodland mansions, I visited almost a hundred woodland mansions and still no invoker. I tested this in my own modpack as well as a brand new profile with only the illager invasion mod installed

There are mods that override the parts of the woodland mansion where the invoker spawns.
If that is the case there is a config option to have them take part in raids so you don't miss out.
For the labyrinth I've noticed myself that it can fail to spawn, but not very often actually.

I tested for another hour only looking for the labyrinth this time, using the /locate command and flying around forests but i was still unable to find any. I appreciate and thank you for the raid config tip for the invoker
