WaterDetect: Unable to clip with a shapefile and 8gb RAM crashed without it

)

I'm trying to run waterdetect with the shapefile clipping option but it seems it cant browse correctly, It gave me 'NoneType' object has no attribute 'FlushCache' error while bands=loader.get_bands_files() gave me an FileNotFoundError: [WinError 3] error for an unspecified path.

Without the clipping option, it ran for an hour and crashed due to lack of ram:

Selection of best number of clusters using Calinski-Harabasz Index: **** ERROR DURING CLUSTERING **** unable to allocate array data

and [str(f) for f in img_folder.iterdir()] gave [] .

So, I'm trying to run :

!waterdetect -GC

water_mask = wd.DWWaterDetect.run_water_detect(input_folder="C:\\Users\\david\\Documents\\py\\myenv\\nakambe_2022\\S2A_MSIL2A_20220101T102431_N0301_R065_T30PZU_20220101T133200.SAFE",
                                         output_folder="C:\\Users\\david\\Documents\\py\\myenv\\nakambe_2022\\output\\water_detect_test",
                                         shape_file="C:\\Users\\david\\Documents\\py\\myenv\\nakambe_2022\\spatial_extent.shp",
                                         single_mode=True,
                                         product='S2_S2COR'
                                        )

or this :

input_folder="C:\\Users\\david\\Documents\\py\\myenv\\nakambe_2022\\S2A_MSIL2A_20220101T102431_N0301_R065_T30PZU_20220101T133200.SAFE"

output_folder="C:\\Users\\david\\Documents\\py\\myenv\\nakambe_2022\\output\\water_detect_test"
os.makedirs(output_folder, exist_ok=True)

shape_file="C:\\Users\\david\\Documents\\py\\myenv\\nakambe_2022\\spatial_extent.shp"

water_mask = wd.DWWaterDetect.run_water_detect(input_folder=input_folder,
                                         output_folder=output_folder,
                                         shape_file=shape_file,
                                         single_mode=True,
                                         product='S2_S2COR'
                                        )

But it seems it can't clip :

Also,

bands=loader.get_bands_files() gave me FileNotFoundError: [WinError 3] Le chemin d’accès spécifié est introuvable: 'C:\\Users\\david\\Documents\\py\\myenv\\nakambe_2022\\S2A_MSIL2A_20220101T102431_N0301_R065_T30PZU_20220101T133200.SAFE\\AUX_DATA\\GRANULE

which is curious because I didn't specified ...SAFE\\AUX_DATA\\GRANULE.

It seems it can't browse correctly. If I delete the \\AUX_DATA folder, then the same error occured but with another path that wasn't specified neither : ...SAFE\\DATASTRIP\\GRANULE, it just tried to reach a folder \\GRANULE in the first folder in the folder \\...SAFE.

I tried also those:
