[Umplayerbr19]

hello, my OS is not booting, i asked that in the Cosmos Discord server, and Quajak told me that the error is in IL2CPU, and told me to open an issue here, ill post the logs and the code of BeforeRun() (where is the error in, according to the logs) below.

LOGS (its in portuguese, and i removed the \Users<user>\ from the path):
