Uncaught FileNotFoundError on Discord RPC connection

Describe the bug
Running Rare from a cloned repository throws this error:

  File "/mnt/dep/dev/Rare/rare/app.py", line 80, in start_app
    self.mainwindow = MainWindow(self.core, self.args)

I do not heave any discord application or account. The current commit I see is 14bd150 .
This following quoted patch fixed the problem but I have no idea what is the meaning of a FileNotFound exception for the connect() function.

To Reproduce

git clone https://github.com/Dummerle/Rare.git
python3 -m venv env
source env/bin/activate
pip install -r requirements.txt
./start

After the initial download of resources the program will quit with the error quoted above.

System information:

• OS: KDE neon User Edition 5.21 based on Ubuntu 20.04
• Python version: 3.8.5

That's a weird error. Maybe you have a corrupt python installation.

I will add the except FileNotFoundError block to avoid this error
