[Eeglablist] eeglab broken after latest Matlab and EEGlab installed

Wed Jul 30 13:49:56 PDT 2025

Hi,

I am running EEGLab2025.0.0 with Matlab 2024b (PC) and am receiving the
following error:

>> eeglab

ans =

    'Error using get
     Invalid or deleted object.'

Warning: could not access the local eeg_options file
Error using get
Invalid or deleted object.

Error in eeglab (line 412)
    if ismatlab && get(0, 'screendepth') <= 8

Any help would be appreciated.

Best,
Shawn
