<p>Hello Alister,</p>
<p>in the meantime I did an update on a second computer from QGIS
3.20.3 to QGIS 3.22.0, and from QGIS 3.16.11 to 3.16.13 using the
OSGEO4W installer. The result is:</p>
<p>QGIS 3.22.0 displays the GRASS init error, the GRASS 7 plugin
cannot be used, the GRASS processing algorithms are working.</p>
<p>QGIS 3.16.13 is working without any problems. Both, the GRASS 7
plugin and the GRASS processing algorithms can be used.</p>
<p><br>
</p>
<p>As far as I understood the GRASS 7 plugin in QGIS 3.22 'want to
see' a GRASS version which is not installed whereas the GRASS 7
plugin which came with QGIS 3.16.13 is satisfied with the
installed GRASS version. But I do not have any idea how telling
the GRASS 7 plugin of QGIS 3.22 that it should take what is
installed.</p>
<p><br>
</p>
<p>Regards</p>
<p><br>

Hello QGIS User Group!<br>
<br>
Today I did the update from QGIS 3.20 to 3.22 using the
Win10 64bit?<br>
installer 'osgeo4w-setup.exe' provided on the QGIS
homepage. When I<br>
opened the new QGIS version I received the following
warning:<br>
<br>
?GRASS init error : Problem in GRASS initialization,
GRASS provider and<br>
plugin will not work : Module built against version<br>
2021-10-11T09:56:15+00:00 but trying to use version<br>
2021-11-01T10:26:16+00:00. You need to rebuild GRASS GIS
or untangle<br>
multiple installations.<br>
<br>
Obviously, something does not fit. But what?<br>
<br>
Are there any ideas? I also did the update from 3.16.11
to 3.16.13 (the<br>
LTR versions) and did not this problem...<br>
<br>
<br>
Thank you<br>
<br>
<br>
Martin<br>

<div>I installed 3.22 today using the standalone Windows
installer, not the OSGEO4W installer, and I got the same
error on startup.</div>
<div>Both the Grass Plugin and Provider show in the plugin
manager as loaded, but I haven't tried using them to
confirm it is truly broken. </div>
<div>I note that the Grass processing algorithms do still
work.<br>
