Toolbox failed

Hey,

I downloaded a toolbox for ArcGIS Pro and tried to run it. It shows the following error:

Traceback (most recent call last):
 File "C:\Users\mprit\OneDrive\Dokumente\ArcGIS\Projects\MyProject\Basinga_ArcGIS\Basinga_ArcGIS\Prod_rates_01_2023_pro.py", line 1782, in <module>

   bot_lat    = float( arcpy.GetRasterProperties_management(DEM, "BOTTOM"     ).getOutput(0) )
ValueError: could not convert string to float: '4696749,62706379'
 

I have now idea about python so I dont know what to do. I hope someone help here.

Best wishes
