How to fix bitcrush audio

I want to fix bitcrush audio in Audacity. Please help me!
Audacity Version: 3.7.3
OS: Windows 11

A quick search turned-up: 11 Free VST bitcrusher effects.

I don’t know if any or all of them are compatible with Audacity. Compatibility is up to the effect developer and with free plug-ins they usually don’t tell what hosts they support so it’s usually just hit-or-miss.

P.S.
Oops, I missed the “fix” part.

If you’re trying to reverse the bitcrush effect, than sounds like the audio-equivalent of de-jpg.
