The code ran an error

[hpgd007]

Hello, I have a problem with your code that cannot be solved, in the main function Graphics::Graphics(const Graphics &)": tried to reference the deleted function,It seems that the data member calls the deleted or inaccessible function "std::mutex::mutex(const std::mutex &)", so the function has been implicitly deleted.I really don't know how to solve it, if you can give me some advice, thank you very much!

Hi, @hpgd007, I will check it, its been a while since I wrote the code, I hope I will find the source of the error.

Thank you very much for your reply, the location of the error is displayed in line 81 of the main function, Graphics viewer = Graphics(windowLength, windowWidth, warehouse._map);After running, an error will be reported showing that an attempt was made to reference a deleted function
