I have a big Problem. In the Python Arcade Library on the newest version (on Version 2.5.7 the Programm running successfull) is this error on the start from every programm:

The code is not important. The Error is on every Programm. I use PyCharm on Windows 10
Its something in the arcade code. Not in mine. Please help me :)
int is a singed data type (See Data Type (GLSL)). 4294967294 is hexadecimal fffffffe. This value can be stored in a variable of type uint (unsinged int), but not in a variable of type int. The maximum value that can be stored in int is 2147483647. For the data type int hexadecimal fffffffe is -2.
Either use the data type uint or change the constant from 4294967294 to -2:
if (vertex_id[0] == 4294967294) return;
if (vertex_id[0] == -2) return;
