@martymcfly7 hello !
Same issue for me on a different plateform.
A desktop x86 PC (old intel NUC) with 6.1.1...
But, I found a temporary solution to play emulator.
Go to the web interface (http://yourrecalboxip) and launch EmulationStation in the support section.
It seems to be an issue with ES !
It's not a definitive solution, but you Can use it.
Hope that start to help you...
