Error media encoder

Hi,

 When I create a proxy of a video with Premier Pro, it gives me an error when I open media encoder. While it’s opening, appears the following error:

 “Adobe Media Encoder has encountered an unexpected error and cannot continue.”

 And after that, it closes. But, if I open it separately, it works correctly.

 I have tried to install a previous version of Media Encoder and now it does not give an error when opening, but when the program is opened, no queued file appears.

I don’t know what to do…

INFO:

 macOS Catalina.  V10.15.4

 Premier Pro 14.0.4

Media Encoder 14.0.3 (Files do not appear), 14.0.4 (Error when opening).

I need help I cannot continue without creating a proxy…

Thank you!
