Facing issue in RawCurry object

I load a curry file but down my data analysis pipeline I am getting the following error.

AttributeError: 'RawCurry' object has no attribute '_data'

Can someone help me debug this. I am using the open-access dataset hosted at Ultra high-density 255-channel EEG-AAD dataset | Zenodo for my analysis. To load the data file I use the following.

raw = mne.io.read_raw_curry(<file_name> + '.dat')

I am able to plot the data after loading it.

Setting preload=True helped address this. Thank you.

raw = mne.io.read_raw_curry(<file_name> + '.dat', preload=True)
