This message is telling you that QGIS cannot find qgis_app.dll on any of
the paths of the PATH variable defined in the listed .env file.
Hi Stewart,
the error doesn't say that QGIS cannot "find" qgis_app.dll, but that
QGIS cannot "load" qgis_app.dll. This means that there is an issue in
qgis_app.dll or in one or more dll that qgis_app.dll depends on or that
one or more dll that qgis_app.dll depends on are missing in the path
defined in qgis-ltr-bin.env (if present).

Well, burned by a QGIS installation again, and this time a LTR version late in
the game.
The latest QGIS 3.22.8 and QGIS 3.26.0 OSGeo4W Standalone Installers for
Windows suffer of the "could not load qgis_app.dll" issue, on some
specific system, already reported multiple times e.g. in
https://github.com/qgis/QGIS/issues/49148 and
https://github.com/qgis/QGIS/issues/49159.
Usually this issue is preceded by a crssync.exe error during the
installation procedure. Did this error also occur?
In such systems, the issue is due to the tiledb.dll library which was
built with the AVX2 x86 instruction set extension. Such library will not
load if the CPU doesn't have the AVX2 x86 instruction set extension.
What is exactly your CPU?
Does it support the AVX2 instruction set extension? If not, then it's
very likely the issue is due to tiledb.dll.
Anyway the issue with the tiledb.dll library has been fixed in the
OSGeo4W repository. So, if your CPU doesn't support AVX2, then you could
install QGIS LTR (3.22.8) using the OSGeo4W Network Installer.
If your CPU does support AVX2, but the qgis-ltr-bin.env file was not
correctly created during the installation procedure, then you could find
useful this comment

With us it was a opencl.dll which is wrongly copied/not removed by Windows (see
links in the post).
Hi Richard,
see also the previous response to Jeff Sonnentag.
Best regards.
