Interoperability between Visual Studio 2019 and Big Sur 11.1

I have MacBook Pro 16 inches.

I recently ACCIDENTALLY updated to Big Sur 11.1

This was my biggest mistake I have ever done in my life.

Anyway, I have multiple issues with this version.

However, I have just one application I would like to fix as soon as possible.

Which is Visual Studio.

I bought this laptop in order to develop a game.

So I am using Unity. And also using Visual Studio to write some scripts.

However, since I have updated to Big Sur, I cannot open Visual Studio anymore.

Once I open a script, application open with full screen, but no response and it just gets crashed.

This is before I open the script on Unity.

This is how look like when I open the application.

Of course I tried to open it from Visual Studio itself, but it did show the same thing to me.

This is freaking inconvenient and I cannot make any progress since then......

Big Sur is really trash. I would like to downgrade.

However, if someone has faced this issue and had any solution, please kindly let me know.

That would be much easier.

Visual Studio 2019's version is 8.6.1.26

Sincerely,

Tokio
