GRASS 7 plugin not working with QGIS 3.22.0 (Module built against version ... but trying to use version ...)

[andreaerdna]

Using QGIS 3.22.0 installed via the OSGeo4W v2 Network Installer (qgis 3.22.0-4) or the Standalone Installer (QGIS-OSGeo4W-3.22.0-3.msi), it is not possible to use the GRASS7 plugin (qgis-grass-plugin 3.22.0-4, grass 7.8.6-6).

The following error is reported in the Log Messages panel:

2021-11-11T11:36:45     WARNING    GRASS init error : Problem in GRASS initialization, GRASS provider and plugin will not work : Module built against version 2021-10-11T09:56:15+00:00 but trying to use version 2021-11-01T10:26:16+00:00. You need to rebuild GRASS GIS or untangle multiple installations.

The issue doesn't occur with QGIS 3.16.13 from OSGeo4W v2 (qgis-ltr 3.16.13-1, qgis-ltr-grass-plugin 3.16.13-1, grass 7.8.6-6) and with QGIS 3.23.0-master (qgis-dev 3.23.0-124-a119884d35-1).

It seems the issue is now fixed with the latest packages and Standalone Installer QGIS-OSGeo4W-3.22.0-4.msi
