[Mne_analysis] mne.io.Raw filter function. Type error: ...must have a dtype of np.float64,

[Alexandre Gramfort]

you are doing:

data_EEG.apply_hilbert(n_jobs=1, envelope=False)

which operates in place and so next time you want to filter
you have complex valued data.

you need to do

raw_hilbert = data_EEG.copy().apply_hilbert(n_jobs=1, envelope=False)

please close if you confirm.
