Crash when editing imgui demo.

I am getting a crash when I try to run game which is based on the imgui demo.

/home/shadowblitz16/RiderProjects/PlatformerEngine/PlatformerEngine/bin/Debug/net5.0/PlatformerEngine

🤔 I am not sure what happened, but here is information i can provide for you:

• LoveSharp.Imgui need LoveSharp nuget library but not Love2dCS
• the best way to run the deamo is clone all of this : https://github.com/endlesstravel/LoveSharp.Imgui

I think it installs LoveSharp as a dependency.
also I based it off the demo there.
