recording level too high or low, There's no gradation.

This is why we strongly encourage limiting topics to one question only.

Almost certainly NOT due to the microphone.

Voicemeeter + Skype + discord. That’s a very complicated sound system with lots and lots of things that could cause problems.

If I were to attempt trouble shooting this problem, I’d start by ensuring that a minimum number of programs and processes start automatically (disable Skype, discord, Voicemeeter and all other non-essential programs from starting automatically).
I would then set Audacity 2.3.2 back to default settings (delete the contents of Users<username>\AppData\Roaming\audacity), and then reboot the machine.
After the computer has fully rebooted, I would attempt to record directly from the USB microphone, with no other applications running.
