Spyder 5 (Standalone) - Does not Start

Pretty newbe in Python programming and completely with Spyder IDE, am I trying to install the software on windows 10 64 but I cannot start it.

It crashes at launch when the splashscreen shows "Loading toolbars" I tried to start the software through the terminal using: python -m spyder.app.start

but I get the following errors:

During handling of the above exception, another exception occurred:

I tried to reinstall Spyder, upgrade the linked plugins, do it admin, local, through pip, through the exe installer (again) tried also the spyder --reset function. it did not work.

I tried to solve the qtawesome issue too but:

I cannot install the TTF or OFT file (get the message "Is not a valid font file")
I Tried to do the solutions here: https://learn.microsoft.com/en-US/troubleshoot/windows-client/shell-experience/feature-to-block-untrusted-fonts. But even in Reg, Python is not listed inside..

Could someone help me to find a solution?

Thank you and have a great day.

Solution

Many thanks to Daniel Althviz. It was indeed the font which was blocking the Gui generation.

Using the icon_theme = spyder 2 in C:\Users\<your user>\.spyder-py3\config the problem was solved.
