Error "ERROR 1990 CAT-SIN 100349" and Error in polr(phenoFactor ~ ., data = confounders, Hess = TRUE): attempt to find suitable starting values failed

[FleetingA]

After running the script and inspecting the results, I notice that a very large proportion of my tested phenotypes produce the below error:

1940_2|| CAT-SINGLE || Inc(>=10): No(30795) || Inc(>=10): Yes(10353) || Inc(>=10): Do not know(1850) || Inc(>=10): Prefer not to answer(68) || [1] "ERROR 1940 CAT-SIN 100349"

or

ERROR: 2050 Error in polr(phenoFactor ~ ., data = confounders, Hess = TRUE): attempt to find suitable starting values failed

Has anyone figured out what might be causing said errors?

Thanks in advance for any advice!

please supply a minimal reproducible example (with test data not real data) and I can take a look.
