I tried to beat every single trial in one single stream and YouTube deleted 6 hours worth of footage towards the end

I want to make sure I don't give the wrong impression. I am not big creator or youtuber. I am a broke CS student and I just stream sometimes with friends for fun. So I had this idea about what if I try to beat every single trial (mk challenges included) in one single live stream. It wasn't about making money or anything (my channel is insignificant af lol) but just a fun idea I had to spend my time off till my next semester starts. I had attempted this many times but failed. But in my 4th attempt last day I started streaming around 1 pm IST and finally beat the challenge by 7 am today.(im dont remember the time that well). My stream started and ended completely fine. It even shows 17 hours and 18 minutes worth of footage last day when I checked but today I see it is suddenly just 11 hours 56 minutes. Rules weren't anything too serious just -

I try to beat every single Trial and MK Challenge in the game in sequential order.

Dying on either map resets me back to the first trial on that map.

Difficulty cannot go below standard.

Revives are allowed.

I must complete a rebirth as well to finish the challenge.

Rigs are allowed.

I had to still sit and play through hours worth of trials even going afk at times to get food or cool down my laptop and i only got sleep after i finally achieved it. But now today I check and the footage is cut off at the start of Pleasure the Prosecutor.

YouTube's help page is immensely overcomplicated and I figure out anything for the love of god (yea shocking that im a CS student). Idk what to do anymore. I don't even know if this is the right sub reddit to post this on (I barely use reddit). But this community is way nicer than other subreddits I have been too and I really don't wanna get ratio'd (especially after suffering through hell in game for hours with my footage now lost).

Anyone got any tips what I should do next. I really don't want to attempt the run again.
