The version of Visual Studio is unable to open .rptproj

Question

I'm getting the error

The version of Visual Studio is unable to open the following projects.
....
"MyProject.rptproj"

I've seen this thread talking about the same error: Unable to upgrade a Reporting Services project to Visual Studio 2019 But the answer to it about installing Microsoft Reporting Services Projects extension didn't solve my problem. I have Microsoft Reporting Services Projects, SQL Server Integration Services Projects, Microsoft Analysis Services Projects and Microsoft Visual Studio Installer Projects extensions installed and enabled. I tried disabling them, reopening VS, enabling them and reopening VS again, that didn't help. I also tried restarting my computer. Everything in SSRS is also configured properly. I also have SQL Server Data Tools installed in VS. Has anybody encountered this issue? Thanks in advance

Upd: Installing installing Visual Studio Extension Development in the VS installer didn't help, also My Visual Studio 2019 version is 16.11.11

Another note: Even though I have Live Share disabled in VS Installer, I am still also getting Cascade Package warning:

Answer 1

I had to download "Microsoft Reporting Services Projects" extension for my IDE "Visual Studio 2019" to fix that error and open my rptproj correctly.
