Roblox Studio "Login Failed" and Worse Connection

Since yesterday, my ROBLOX Studio has been showing me this error (below) almost every single time I open Studio.

If I hit “Log in through Browser” or “Try Again” enough times, it finally lets me in. But even after that, my connection to ROBLOX is significantly worse. Meshes often don’t load, it takes a while for me to play test the game, and uploading assets takes TREMENDOUSLY longer.

I reinstalled Studio and removed all the AppData on my computer, and yet this issue still persists. I’m (somewhat) confident it’s not my internet connection because all every other application my computer runs perfectly fine.

Is anybody else experiencing this or is it just me? Thank you!

also have been experiencing this but usually during times when roblox is most busy
for like the past 6 months
