I am assuming you are trying to run something in Ansys MAPDL solver in batch.
It appears to be choking on the MP command.

It does not appear to recognize the label "UVID" as a supported material property.

Also, "725FFBA5-37FA-45C3-840A-B9ACA5016EB8"   is not a recognized numerical property or parameter.

Please refer to the MAPDL commands manual for MP and TB for details on what Labels are supported and for supported command syntax.  I have no idea how this worked without issues in previous runs.  It seems like something is missing upstream.
