I encountered this recently with the X2T-F (most recent firmware) simultaneously on my xt4 and gfx50s - I just spent an hour on troubleshooting and (for me at least, and for now) this worked:
disable the LED AF switch on the godox transmitter, make sure that LED AF is also turned to "off" in the TTL settings of the camera body.
fired a couple of hundred strobes like this with both bodies with no freezing occuring.
firmware xt-4: 1.23
firmware gfx50s: 4.30
firmware godox x2t-f: 1.1
I've tried a number of lens hoods, but they all have the disadvantage of not being able to fit the lens cap when not in use.
This one is specifically designed to take the standard lens cap and even has a soft rubber ring to ensure a snug fit.
Very nicely made in anodised aluminium.
