Error while running SAGA algorithms in QGIS 3.10.14-A Coruña

Question

I've been trying to run several hydrological algorithms (Strahler, Fill Sinks etc) from SAGA in QGIS ltr and I keep running into the same error:
The following layers were not correctly generated.C:UsersHANNES~1.BYSAppDataLocalTemp/processing_54346125960a43788d22bdb05d351ac6/a33e5a9db9f7418e8b1c75f5b08eac12/STRAHLER.sdatC:UsersHANNES~1.BYSAppDataLocalTemp/processing_54346125960a43788d22bdb05d351ac6/ffe2e0caaf2c4a5a9f12648fa77f4364/STRAHLER.sdatYou can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm.
I've reinstalled QGIS via OSGeo4W and stand alone installer and I've also reinstalled SAGA.
Here is a picture of my workflow:

So I've managed to solve the problem (sort of).
It seems that SAGA doesn't like input in the form of GeoTIFF and after converting the input to .ASC via GDAL Translate, the algorithms started to work (although still ending with the same error).
Update
After some additional testing, it seems that SAGA is more likely reacting to my specific input of GeoTIFF which are compressed. Now, when I decompress them and keep the file format, it yields the same result as previously listed (the SAGA algorithms produce output but still leaves an error).
