Keeps telling Me that "Something went wrong in the login process

I recently updated Minecraft and i saw both of my accounts ready to be clicked but it seemed that the Main account that i use (Which I had for years when i bought Minecraft for My MAC) couldn't be used and the other account which i never use and never merged with anything, could be used but can only be played on the demo mode. This never happend before and I'm wondering if it's a bug or something but I've been waiting almost a week for it to be fixed and with the Pre-release of 1.18, I saw that a lot was fixed but I saw none of them was the one I needed fixed. Don't know if it's just me or others but I really want to play Java Minecraft.
