Virtual key presses only work some of the time

[BrianTheBrain11]

Im using InputSimulator to simulate keyboard inputs, but they only work some of time, its not consistent. How could I make virtual inputs from a separate class? I'm trying to hook up a discord bot and I have that running on a different thread of the program, and while using the bot to make virtual keypresses works on every other program, it doesn't work on the CrystalBoy program consistently.
