Slow Blazor wasm build in Visual Studio 2022 .NET 5.0 based

[regression] [worked-in:2019]
I have a quite simple Blazor WASM app, created from the Blazor client/server template. Besides Blazor client and server projects it also has three more library projects. All .NET 5.0. Everything works in Visual Studio 2019. The solution builds in 5 seconds.
When I open it in Visual studio 2022 release (and I've noticed that behavior in the preview), the same solution hangs for about a minute during the build. "dotnet build" from the command line - 5 seconds . When I build library projects individually - compile time is almost instant. When I change project bindings to .NET 6 - the build is under 5 seconds. Back to .NET 5 - a minute.
I cannot upgrade to .NET 6 at the moment.
Please advise.
Thanks.
