[SOLVED] The new ,,modern" youtube design is garbage and unusable. How can I change it?

So about 3 days ago my YouTube look changed and now I cannot use it because of the ,,modern", rounded and simplified look. The thing is, if I go into incognito mode, youtube looks normal. I heard someone say that youtube can try their BETA designs on random people's accounts. Is this changeable?

How I see it from my account :

How I see it in Incognito Mode (normal) :

I know this might not be a big deal, but the main problem is that I cannot watch the oldest videos, the description is a whole different story. I hate the era that we are in, where everything must be simplified, rounded and ,,modern" looking.

Well, you must be one of the ones they are trying it out on then because it doesn't look like that for me and as far as I am aware of or can see after looking through all the options on there, there is no way to change the site layout or design. There simply are no such options on YT that I am seeing.
