unity 2020 - No compile params for Assembly-CSharp.dll

[nanonull]

When starting game I see as expected: [hotp] Assembly Reload locked as entering play mode

But when patching in unity 2020 there are logs: [hotp] No compile params for Assembly-CSharp.dll. It's likely that assembly has yet to be compiled during current session [hotp] No compile params for Assembly-CSharp-firstpass.dll. It's likely that assembly has yet to be compiled during current session

I've made code changes in some method body before patching.

Project player config: Scripting backend = Mono Api compatibility level .NET 4x Allow unsafe code = true

Also Temp/hotswap.log is empty
