I turned on a VPN and it started updating the launcher. I was using a mobile internet connection though, and I think that's why it didn't work. I couldn't find any mention of trying a VPN to fix it anywhere, but I remembered that it's fixed similar problems in the past. And viola
I look forward to your reply and am ready to collaborate until we reach a resolution. Best of luck!
