Hey guys. I am having an issue with my game but it isn't giving me a lot of info about the crash.

When I start the game from the launcher, it will try to load then give me this:

Error: Could not create the Java Virtual Machine

Error: A fatal exception has occurred. Program will exit.

I close that then it brings the Launcher back up with the crash error:

[0x7FFFF65B42A0] ANOMALY: meaningless REX prefix used
[0x7FFFF65B4150] ANOMALY: meaningless REX prefix used
[0x7FF81770B8F0] ANOMALY: use of REX.w is meaningless (default operand size is 64)

[0x7FFFF736CDB0] ANOMALY: meaningless REX prefix used
Invalid maximum heap size: -Xmx

The only thing I understand from it is the last line. When it comes to my JVM arguments, this is what I have in my profile:

-Xmx 8G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

Up until about three weeks ago, it was working with no issue as is. If anyone has a fix, I would be grateful.

Thanks!
