Describe the bug I've never asked about this so i will right now so when i download it it supposed to be downloading inside the 'download' folder but idk why it saved outside the download folder and saved as 'downloadvideo_9333.mp4.mp4' or 'downloadaudio_9333.m4a.m4a' it works fine with version 7.0.0 but it doesnt work on the newer after version 7.0.0 it saved like that like doesnt want to save inside the download folder it just save as the folder was the filename and double extension

code that was used that resulted in the bug

Additional context Idk if its my code problem or the package problem i'm still a high school student so i don't really focused on coding since coding it's just my hobby my school doesn't teach how to code

remove .mp4 and .m4a, pytubefix already does this, otherwise it will be duplicated

well yap that one of my problem the main problem is it act like the i set the download folder instead it saved on download folder it saved like outside the download folder and the download folder act like filename it works perfectly in version 7.0.0 after that idk why it doing that

Flask's send_file should already do this job, test without using output_path

still it save file outside the download folder could you maybe try it?
