Hi Jeff, Can you check this: https://qgis.nl/2021/11/05/qgis-on-windows-oops-could-not-load-qgis_app-dll-message/
With us it was a opencl.dll which is wrongly copied/not removed by Windows (see links in the post). Short version: make sure you have the good copy of opencl.dll either in the QGIS install dir OR in the c:/windows/system32 directory. See https://github.com/qgis/QGIS/issues/44806#issuecomment-908976764 for more info about it. HTH, Richard Duivenvoorde On 7/6/22 03:31, Jeff Sonnentag via Qgis-user wrote:
