No desktop app, no app button on Teams

I'm on an MS365 personal account. I tried to add the "apps" to Teams. I've tried changing permissions, running it as administrator, and changing the settings. So, I find out "If the Apps button is missing, it may be due to policy settings or the user's account type. For instance, the button is not available for personal Microsoft Teams accounts. Users can try using the web version of Teams or check for updates to the desktop app."

I tried the web version and it's not there either. No apps button.

So, I uninstalled and reinstalled the Teams desktop app. Now, I'm prompted the Store couldn't open the app and directed me to go to the Start menu. I did. Teams does not show up. I can't use the desktop version at all.

Why can't I reinstall Teams? How do I fix this? And why is MS not allowing the "Apps" function on personal accounts? Is there a workaround?
