I tried to start up Minecraft, but it was stuck on the "Finalizing" process for 15 minutes straight. I closed the launcher, but when I opened it up, it was still "Finalizing" yet did not let me pause or cancel the process (the buttons did appear, but they are unclickable) and has locked me out of starting the game. I ended the task via Task Manager (this is a Windows launcher) but it still was "finalizing." So I resorted to restarting my computer, same story. I tried uninstalling and reinstalling the launcher, same issue.

As for the information, my launcher has been stuck like this for 2 days, so I can only attach a screenshot of the issue. Hopefully, this is sufficient information to find the cause (even though it might not).

Edit: Never mind, I managed to record a video of the still-prevalent issue. I cannot record longer than this, otherwise it would exceed the 10.00 mb limit
