My microphone on the laptop no longer works?

Today I installed an app called clownfish it was a voice distortion app and it worked out pretty well at the beginning. But later I noticed that my microphone suddenly stopped working, then I looked on YouTube to see what the problem is, but everything that occurred in the videos was correct for me, my microphone works properly according to Windows, but when I use apps like discord can't go please help me i need it!

Open the sound settings with a right-click on your volume symbol and then see whether the input device says something with Clownfish or change the input device.

No, it says nothing about clownfish
