Need help with opus and freearc

[averanted]

Hello guys I have a problem.
I am trying to compress wav files with opusenc and arc.
Compression process works fine but when I try to decompress it, freearc keeps extracting the file again and again and never stops.
I used this command to compress my wav:

arc a -mopus out.bin file.wav

and to decompress it:

arc x out.bin

my arc.ini file

[External compressorpus]
header = 0
packcmd = opusenc {option} --bitrate 320.000 --comp 10 --quiet --framesize 60 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = opusdec $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

[External compressor:flac]
header = 0
packcmd = flac {option} -f -8 -o$$arcpackedfile$$.tmp $$arcdatafile$$.tmp
unpackcmd = flac {option} -d -o$$arcdatafile$$.tmp $$arcpackedfile$$.tmp

Output from cmd:

I pressed Ctrl+C to stop it.

With flac and it worked fine.

I think I know why it works for flac but not for opus.
opus's output is lossy but arc is trying to get the original wav file which is not possible.

Is there a way to stop arc after first attempt.

Sorry if all this is stupid, but I just came to know about arc.ini is and what it does.
