Cannot run program "/data/user/0/xxx.xxxx.xx/files/ffmpeg": error=13, Permission denied

Question

friends, when I want to export, a sub error occurs on my android 10 device and the phone freezes. I just couldn't figure it out.

I don't know what caused the error I added manifest - requestLegacyExternalStorage still not resolved.I get it when I start rendering in a video rendering application as an insert.
