EEGlab ICAlabel not working with specific data

I have 64 channel EEG data run through preprocessing steps before running ICA. I have run 18 datasets using the same process with no issues. I have 2 datasets where the ICA takes hours and then once the ICA is finished, this error occurs:
Error using ICL_feature_extractor (line 26)
Your ICA decomposition must be real to use ICLabel
Error in iclabel (line 52)
features = ICL_feature_extractor(EEG, flag_autocorr);
The data doesn't look any different than my other datasets. Any suggestions?

Which error?

iclabel appears to be a third-party toolbox.
You could get that message if your ica generated nan or inf or complex values.

Can you expand on what you mean by nan or inf or complex values? And how do I correct for that? Even the function in eeglab to "inspect/label components by map" doesn't work.
Still learning matlab and eeglab and I haven't seen this error before.
What shows up for
nnz(~isfinite(EEG))
if the result is not 0 then you have samples that are infinite or Not A Number (nan). nan is often used to indicate missing data.

Hi @Rebecca Kenny, did you get around to solve this error? I seem to be facing the same error with my 9 channels EEG data.
