When I open up Godot, it seems to mostly work normally, except it keeps a second window open the whole time, containing an error message. If I shut this window the main Godot window also shuts.
I've been doing some tutorials on Godot, and it's seemed to work normally, until now. For my project one of nodes isn't detecting a 'signal' sent by the other node. I'm positive I haven't made an error, the only thing I can think of is this. I fear the only solution may be to get new hardware, since I'm working on my laptop which is fairly old and low-powered, and after doing some Googling it seems my laptop's processor might just not be able to run all of Godot properly.
Here is the error message:

My computer's processor is a Pentium(R) Dual-Core CPU T4500. It is a Dell laptop that runs 64 bit windows.
Is there any solution (such as using a different version of Godot)? Or is the only solution newer hardware?
