Now I can use version 5.0.00 of Live2D.
I don't know if this is because I connected XPPen Artist 12 Pro to mainboard, because after I connected all the monitors to the Nvidia graphic card and tried to run Live2D as an administrator as usual(not run compatibillity mode (win 8) ), so I could open version 5.0.00 of Live2D!
Another way I got from my friend is properties -> run compatibillity mode (win 8). It works too!
here is my log file, in case it is useful or know another reasons.
sorry for my poor English.
java.lang.UnsupportedOperationException: Unsupported GLProfile.GL3It seems that somehow your GPU - RTX 4070 was not being used when the program was running.
Anyway, I'm glad you solved the problem!
