Video Filter missing: AE.ADBE Aud Stereo Mixer

[DAVIDE PEPE]

When I open several old projects (3-4 months ago so not so old) I get the error "Video Filter missing: AE.ADBE Aud Stereo Mixer" and when I play the sequence timeline the sound is distorted.

Please can anybody tell me how to bring AE.ADBE Aud Stereo Mixer back?

Have a nice day,

Davide

Import into new project instead of open.

Hi Ann!
Thank you. I had already tried it but it doesn't work. I keep getting that error.

Hi Davide, I'm also getting the same issue. I'm using Premiere Pro 2020 14.0. 

Also, are you facing the video being laggy after exporting? I'm facing this as well.

Did you find any solution yet? Please lemme know, thanks :'
