GRASS 8.5 Not working

Last week I updated my GRASS 8.4 to 8.5.0 and my QGIS 4.0.3-2 to 4.2.0-Belém do Pará using the OSGEO4W Setup on a Window 11 computer.

QGIS is running perfectly but now GRASS is not functioning.

GRASS GUI starts correctly. My existing projects and all the raster/vector layers are visible in the data window.

But when I try to display them on the map I get the following error with nothing displayed:

Failed to run command ‘d.rast map=srtm30@PERMANENT’. Details:

If I try r.patch, it runs and never stops and nothing is produced.

I tried creating a new project/location it still failed in the same way.

I completely uninstalled 8.5.0, rebooted and re-installed 8.5.0 and no improvement.

I then, uninstalled 8.5.0, installed version 8.4 and now it won’t work either.

Between one of my un-installation attempts I even when through the filesystem and removed all the user profile configuration files.

Does anyone have any suggestions on how to fix this? Or am I the only one with this problem?

I have a few hundred stream sediment catchment polygons to extract from a very large LIDAR DEM so I really need GRASS working!

regards,

Phil

I don’t have a good understanding of what happened, but in the meantime, try the 8.6.0dev from osgeo4w, an « independent » install, and will allow you to start from fresh, ideally, until you figure out your 8.5 install
