Installer-based Spyder does not start on Windows

[giumas]

Using the latest installer, Spyder does not start on Windows. It only shows the splash screen, then nothing else happens. (How to activate the console or debug logging?)

I suspect that it is related to spyder-ide/qtawesome#167 because it works when I change the Untrusted Font Blocking setting (described in https://docs.microsoft.com/en-US/troubleshoot/windows-client/shell-experience/feature-to-block-untrusted-fonts). Unfortunately, the listed solutions in the Microsoft page cannot be applied on the target machines.

Hi @giumas thank you for the feedback! I think you are right although maybe we should move this issue to the Spyder main repo to keep track of it, what do you think @ccordoba12 ?

Besides that I guess checking if we can somehow try to install the fonts for the current user could be quite useful. If you get to know more info regarding that process let us know at spyder-ide/qtawesome#167 (I started checking and searching but not yet there so any help is quite appreciated!)

Yeah, this issue doesn't belong here. @dalthviz, please move it to our main repo.

Note: For now fix the fallback to the Spyder 2 icon set so if the icons are not available due to the font load error, Spyder should use the old Spyder 2 icon set which doesn't rely in loading fonts.

By the way @giumas to debug you can launch the installed Spyder from a terminal running the Target specified in the generated shortcut and changing pythonw.exe for python.exe. It should be something like this (where <your user> is the current session user directory):

C:\Users\<your user>\AppData\Local\Programs\Spyder\Python\python.exe "C:\Users\<your user>\AppData\Local\Programs\Spyder\Spyder.launch.pyw"

If you want even more information you can run it with the debug-info verbose flag, so something like this:

C:\Users\<your user>\AppData\Local\Programs\Spyder\Python\python.exe "C:\Users\<your user>\AppData\Local\Programs\Spyder\Spyder.launch.pyw" --debug-info verbose
