Newbie using it for the first time sadtalker error code questions （Unable to output [duplicate]

Question

I'm a complete novice and I got an error the first time I used it. I plan to use sadtalker to make audio videos. After uploading the video and picture materials, an error occurs after the progress bar runs out. When asking chat gpt, I got the problem of wrong path and duplicate output and input paths. chat gpt tells me that the path of output is the same as that of input, but I don't know how to solve this problem, from where should I change the path of output and input? I would like to know how to solve this error code.Please help me.

web ui shows wrong content in url https://lurl.cc/ETTUC
