High pass filter-nyquist error

Hello,
As I was using audacity (2.3.0) on my computer (Windows 10) I tried to apply the high pass filter to a track, however i got an error notification stating “Nyquist has returned the price:1”(excuse me if the error message is not 100% correctly translated as i am using audacity in greek) and the high pass filter isnt functioning.Can anybody help me with this?
Thanks, George

Try this:

  1. Close Audacity
  2. Go to the hidden folder: *Users<username>\AppData\Roaming\Audacity* and find the files: pluginregistry.cfg and pluginsettings.cfg
  3. Delete the two files: pluginregistry.cfg and pluginsettings.cfg
  4. Launch Audacity and test the High Pass filter.
