The recording is beyond repair. The only really effective "fix" is to re-record it.

Oh. What could cause the distortion?
Maybe some good filter can help?

Something is being severely overloaded.
How was the recording made?

It was made at translator hood using PC+Audacity connected via mini-Jack cable to a mixer.

I suspect that the mixer was connected to the "microphone" input on the PC. That won't work properly because a microphone input is expecting a tiny microphone signal, whereas a mixer provides a signal that is about 1000 times bigger than a microphone signal. Thus the microphone input is massively overloaded.

The mixer needs to be connected to a "line level" input.
Many full size PCs have separate "line" and "mic" inputs - use the "line" input.
Many laptop PCs have only a "mic" input, so you need to use an external sound card that has "line" inputs (I use a Behringer UCA 202, which is about $30).

Understood.
Can filtration help as least to enhance the recording a bit?

Unfortunately not.
You can make it sound a bit less harsh by using a low pass filter, but to have a noticeable effect the would will become very muffled.
