I am an experienced user of ArcGIS desktop.
In the latest version ( now 10.8.1), I am processing raster with various tools (e.g. ArcHydrotool).
The first time I process a raster works fine, but then, any new operation, I get an error message saying the ..tif is not valid... like the following image:
The only solution I found is to retart ArcGIS dekstop, and then it works, but again just for the first processing. For the second processing, the same error appears 'tif not valid'
This is quite anoying because I need to restart the software everytime I have a new calculation step.
Do you have any idea about this error and how to solve it?
Many thanks in advance
