[QGIS-Developer] How to enable debugging mode on QGIS start in Win11

[Vedran Stojnović]

Hi,

I just installed QGIS 3.30.3 via web installer ("qgis-full" version) and
QGIS won't start at all, nor does throw any error when I start it from
PowerShell by executing "qgis-bin.exe".
I tried reinstalling a few times using different servers (default one and
norbit.de) and I also cleaned the cache folder before changing the server.

I already tried adding these two lines to "qgis-bin.env" and I
created "qgislog.txt" on the desktop, but I still do not get any output to
the command line and txt file is empty after trying to start qgis:
QGIS_DEBUG=9
QGIS_LOG_FILE=C:\Users\phidr\Desktop\qgislog.txt

so the current contents of "qgis-bin.env" is:
PATH=C:\OSGeo4W\apps\qgis\bin;C:\OSGeo4W\apps\grass\grass82\lib;C:\OSGeo4W\apps\grass\grass82\bin;C:\OSGeo4W\apps\qt5\bin;C:\OSGeo4W\apps\Python39\Scripts;C:\OSGeo4W\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\system32\WBem
