Adobe make my internet numb and slow

Hello.

I try to update my version of Premiere Pro CC 2019, and for an unknow reason it was stuck at 5%. So I decide to remove the previous version of my Premiere Pro and to reinstall it form scratch. I have fiber, so it's okay. But then it block at 5% too. I decide to reinstall Creative Cloud, but then the problem really start... My internet is 56k. Only on my computer. My phone connected to the house wifi is okay.

So seeing the forum, I downloaded painfully the Creative Cloud Cleaner. Clean everything multiple time (cause why not). Restart my computer a thousand time (I may exagerate, but it's a frustrating experience), and still no solution. I wipe all Adobe product from my computer, cause apparently Adobe is a big issue for my computer. But now, when I try to download the Creative Cloud app, I simply can't. My internet crash. It become 56k.

To conclude : I litteraly can't use my internet when I'm trying to do anything with Adobe, either on the app or the website. Which make me impossible to dl and work.

Please tell me there is a solution to that weird problem (and no adobe cleaner doesn't help sadly)

Cheers
