Empty result at every first run of SAGA raster algorithms

At every new run of any SAGA algorithm that involves raster layers, it gives no output, because it seems to only run

SAGA Version: 7.2.0 (64 bit)

ERROR 1: Can't load requested DLL: C:\OSGeo4W64\saga-7.2.0_x64\dll\gdal_KEA.dll
Execution completed in 2.38 seconds
Results:
{'INVERSE': 'D:/SIG/MDT/testes/dem_inverted.sdat'}

Loading resulting layers
The following layers were not correctly generated.<ul><li>D:/SIG/MDT/testes/dem_inverted.sdat</li></ul>You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm.

In this first run, the temp raster is created by io_gdal 0, importing the input tif raster and transforming it to sgrd in temp folder C:/Users/pedro.venancio/AppData/Local/Temp/processing_46a9a8edada443d68a7c07a0466c2a9a/8fcc35f8e29c4bacabd6b8e8b9082fe1/demsrtmpttm0680mclip.sgrd

But after this, it does not run the main algorithm, in this case, grid_tools "Invert Grid".

Running the algorithm again, as it already has the temp raster in sgrd C:/Users/pedro.venancio/AppData/Local/Temp/processing_46a9a8edada443d68a7c07a0466c2a9a/8fcc35f8e29c4bacabd6b8e8b9082fe1/demsrtmpttm0680mclip.sgrd, just runs the grid_tools "Invert Grid":
