ERROR: Unable to load GDAL library

Hi Nelson,
did you install QGIS 3.22.8 using the OSGeo4W Standalone Installer or the OSGeo4W Network Installer? If the latter, have you updated all the installed packages? If the former, what installer exactly: the QGIS-OSGeo4W-3.22.8-3.msi or the QGIS-OSGeo4W-3.22.8-4.msi installer?
What format is your raster layer? Does any of the GRASS processing algorithm work?
Could you please report the whole processing log?

Does GRASS-GIS starts without issue if launched using the shortcut link? Does the r.series tool works in GRASS-GIS?

I've just tried to run r.series with QGIS 3.22.8 installed using the QGIS-OSGeo4W-3.22.8-4.msi OSGeo4W Standalone Installer and also installed using the OSGeo4W Network Installer and there is no issue with both in my system.

Anyway, right now the new QGIS versions, 3.22.9 and 3.26.1, are available in OSGeo4W Network Installer and the corresponding new OSGeo4W Standalone Installers are available at https://download.qgis.org/downloads/?C=M;O=D

Best regards.

Andrea
