Can somebody please help me with Riot's dog*hit client?

Its funny how a multimillion dollar company can have a client that is so bad in every aspect for years and never fix it, ive seen clients made by developers with a total budget of -50$ that had way better clients, i seriously do not remember a single time where Riot client did not have a single issue and they somehow always manage to have different ones every time.

I reinstalled my Windows and didn't play anything by riot for a while, i wanted some valorant so i downloaded it and there it began, every solution simply replaces the previous problem with another. First game would present some error code 68 on startup, i heard i need to restart pc, didnt work, now i couldn't log in as it said "We are having trouble logging you in", i heard you had to change DNS, so i did, i could log in, now valorant wouldnt start "Failed to launch, something unusual happened blah blah", none of the solutions i found online helped, i switched my DNS back to DHCP, it can start now, but now im back to the original issue, error code van 68, it also wont load my friends list on riot client now.

Can anybody tell me what the actual f*ck is this garbage clients problem? And riot, please for the love of god, fix your damn client. Valorant is supposed to make you pissed off while playing not before you even start the damn thing
