Dear MNE Community：
MNE version: 1.11.0
The system: windows 11
I hope this message finds you well. I am currently working with EEG data that has been preprocessed using EEGLAB, including epoching (using the ERPLAB plugin in EEGLAB), ICA processing, and filtering. However, when attempting to read the processed EEG data into MNE using mne.io.read_epochs_eeglab(datapath), I am encountering the following error:
TypeError Traceback (most recent call last)
