C50A0 Robot powerup issue

I have a customer With a UR10e, Polyscope Ver 5.12.

We have done some Wiring modifications to the Safety (added a Pressure floormat into the Safeguard Stop) and all tested fine.

Now when Powered on in Remote. The Robot reports an alarm C50A0: Robot powerup issue
If I switch to Manual mode the fault still persists.
However If I power on whilst in Manual mode the Fault does not appear and I can swap to Remote and run the program fine.

I have removed all Estops, safeguard stop and replaced with links and still the same fault!

Does anyone have any ideas?

I have found out the problem was not Hardware related but the Installation file

Somehow I think the Installation file had become corrupted.

when I tried a Default file the issue dissapeared.
