[Qgis-user] QGIS 3.xx not starting

[Nicolas Cadieux]

Hi,

I would start with the suggestion below.  Then, I would update all the drivers and try to see what other software is normally auto loaded at startup to see what could be interfering with QGIS (like a anti malware).  Concerning Quickheal, it may have blocked something at the installation so I would uninstall it (or disable it completely) and uninstall  QGIS. Reboot, then reinstall QGIS.

>>> Did you have a working version before or is this a first time QGIS installation?  You have 2 choices of installers on Windows, I would try with the second installer after removing the first version.  Reboot the computer after the installation.  Try Disabling your antivirus or adware software you could have when installing or starting QGIS, make sure your Windows and drivers are up to date.  Do you have a second version of Python on your computer, or a software like ESRI that as it’s own version of Python? Perhaps there is a conflict between your QGIS python and the default python distribution?  If this is not a new install, would you have a problématique python plugin  in the plugin directory? Perhaps try removing those...  Would you have weird character in your user directory like spaces or accents like “é”?

I have also tried "run as administrator" but still the problem persists. With v3.10 and v3.14.1, the same problem is there. I have installed software again with "Run as Administrator" but the issue is not solved.
