SubprocVecEnv not receiving any data

[praetorianer777]

Hello, I have the same problem as #1117.
I am also on Windows 10. DummyVenc works fine, but SubprocVecEnv not.
I don't know what was the problem with observation spaces in #1117 , but the env_check works fine.

My custom environment and also the regular environments don't work with SubprocVecEnv.
Someone has an idea?
