ArcPy unzip geodatabase error code 80004005

I got a zipped geodatabase from a colleague and want to unzip in order to load it to my project. Therefore I run the following command in the ArcGIS Pro Notebook:

import arcpy
arcpy.env.workspace = r"E:DateienArcMap"
arcpy.UncompressFileGeodatabaseData_management(r"Geodat.gdb")

Unfortunately I get the following error message:

ExecuteError: file C:ArcGISGeoprocessingGeoprocessingCompressGPCDFFunctionsCOM_utils.cpp, line 69: Unbekannter Fehler;  (code 80004005)

("Unknown error; (code 80004005)")

the named filepath ("C:ArcGISGeoprocessingGeoprocessingCompressGPCDFFunctions") does not exist on my filesystem but I installed ArcMap on another drive (E) and I can’t find any file "COM_utils.cpp" on my system.

Is my ArcMap installation corrupted or is there another common reason for the error?

System Information: Windows 10, ArcGIS Pro 2.6.0

I don’t use Windows/ArcGIS that often. I’m more a Unix/open source user so I have no clue what is going on.
