I just encountered this same error today on a 2GB Pi4 with this card: https://www.amazon.com/gp/product/B0887GP791

Mine was when hitting the "Update RetroPie-Setup Script".

SAMSUNG: EVO Select 128GB MicroSDXC UHS-I U3 100MB/s Full HD & 4K UHD Memory Card with Adapter (MB-ME128HA)

Fresh installation, and only time this card has been used.

@spud11 I am using the "Filemanager" menu option now. I created a bash script to test how runcommand worked.

But, if as you said, I can create a bash script to invoke joy2key and then mc, I might as well do that.

I did not expect that this kind of change would be so difficult to make :(

@meleu it failed as pi user so i used root user to get joy2key to work
