Files get uploaded but fail to be processed (bug most likely)

I am facing a bug likely .Through chatgpt interface when I upload a file(json,csv,MP4 etc) it get’s uploaded but when I prompt chatgpt to analyze the files , it always replies “code environment was reset” . I am facing this problem for almost a week and I tried contacting the openai support services but there was no response from there end . I rely heavily over chatgpt’s file processing services for my day to day task and without it I am feeling really despair , I also have the plus subscription , can anybody help me with my case ??
