The first calculated eigenfrequency of the full Design Space is lower than the chosen frequency constraint. The optimisation logic isn’t able to reduce material in this case. There is a workaround on the frequency help page.

invalid supportReductionMode … expected off, passive, reactive or active.
Please set the Support Reduction Mode to one of the supported modes.
...
missing / incompatible strutDensity setting for use with support avoidance.
If you are using the Support Reduction, you need to define a Strut Density.

Requested nastran operation but did not specify nastran service. Please set env variable 'EMENDATE_SERVICE_NASTRAN' to point to your nastran binary.
If you want to execute a frequency optimisation directly in the command line, you have to set a environment variable which points to the nast20233.exe
EMENDATE_SERVICE_NASTRAN | C:\Program Files\MSC.Software\MSC_Nastran\2023.2\bin\nast20232.exe |

Cannot inflate geometry with zero vertices
This can occur to a current limitation. Please make sure that a point load or a displacement constraint on a point is not applied at the edge of an interface. Increase the Interface or change the load to a surface instead.

Unfeasible FEM setup: Missing fixation in one or more directions
Check the model set-up. All 3 degrees of freedom have to be constraint.
