I use the VIO Wizard to create a VIO instance. Then I generate the example program and try to implement it. I see this error:
ERROR: [Opt 31-120] Instance 'VIO_INST/inst/PROBE_OUT_WIDTH_INST (vio_0vio_v3_0_probe_width__parameterized0)' has become an empty hierarchy during sweep, however it has constraints that do not permit its removal.
Fortunately for me, this is exactly the same error as I am seeing in my own project, even when I run the VIO outputs to package pins.
Has anyone else seen this?

Can you attach project archive of your simple test case here?
