Cisco Packet Tracer (7.2.1) crashes when logging in [SOLVED]

As the title says, the Cisco Packet Tracer crashes when I enter my e-mail and press the "Next" button.
I installed the packet tracer with the install file, which is included when downloading version 7.2.1. It worked without problems and I can also open it. But after I open it, I need to login, but as said before, when I enter my e-mail and press the "Next" button the program freezes and crashes.

opt/pt721/packettracer: line 8:  1769 Floating point exception(core dumped) ./PacketTracer7 "$@" > /dev/null 2>&1

And when I debug it with gdb I get the following:

0x00007fffef5dbef4 in QFontEngineFT::averageCharWidth() const () from ./libQt5XcbQpa.so.5

The newest version 7.3.0 does work, but unfortunately, I can't use it (because the files aren't backwards-compatible and at my school, we use 7.2.1 so if I use 7.3.0, I can't open them in school).
I already tried to ask them in the cisco forums directly, but unfortunately, they couldn't help me.

I tried already to reinstall libpng12 and openssl-1.0 because they are needed by the packet tracer, but it didn't help. I also tried to install it on Manjaro and it worked, so I think it should also work under Arch. I hope don't miss something major here.

After a few days, I found a solution to the problem. To run the cisco packet tracer I needed to install

ttf-ms-fonts

Now it works.
