Issues installing Teams apps

We are having some issues with installing certain Teams apps and it may just be that I don't understand some things.
In particular, we would like to install App Studio.

Here is the scenario:
Under Org-wide app settings in Teams we have Allow third-party app set to Off.
Under Manage apps I see App Studio in the list of apps and the publisher say Microsoft. Status says "Blocked org-wide". If I highlight it and click Allow I get a popup that says "Allow application? You are allowing this app to be available for users in the Teams app store. However, it won't be available to them if they have a blocking app permission policy." When I click Allow the status does not change and the message across the top of the screen says "All third-party apps are currently blocked. To allow any third-party apps, enable 'Allow third-party apps' in the Org-wide settings".

We also tried enabling third-party apps and in Permission polices setting third-party apps to "Allow specific apps and block all others". We then added App Studio but after doing that we noticed that a lot of other third-party apps were being allowed. So we turned that back off.

So my questions are:
1. Why is App Studio be treated as a third-party app when the publisher is Microsoft?
2. How do you allow one third-party app without then allowing a bunch of others?

Thanks a lot.

@KennyStern-7712,

Question 1. Why is App Studio be treated as a third-party app when the publisher is Microsoft?

This is also confused me. I will figure out the reason. If I get any valuable information, I will share with you here as soon as possible.

Question 2. How do you allow one third-party app without then allowing a bunch of others?

From my experience, it is unnecessary to turn off Allow third-party apps in Org-wide app settings from Microsoft Teams admin center > Teams apps: Manage apps.

Above all, make sure that you want to assign the same policy (only assign permission of app studio but no other third-party apps) to everyone in your organization. Then, modify the Global policy for App permission as below or create a custom policy to assign to the people you want:

It will take effect after several hours. Even if users can search other third-party apps in client, they cannot add these apps to Teams by an prompting message “Something went wrong”. So, don't worry about it.

So you are saying it's normal for a whole bunch of apps to appear in the client even though I'm only allowing the one, but that they won't work? And there is no way to keep them from appearing at all?

@KennyStern-7712,
I mean it needs some hours to hide all blocked apps in Teams client. Before that, users can still see these apps but cannot use them. Hope I explain this clearly.
