I'm trying to randomize Pokemon Vandy DX [Help]

[Shadoxas]

3DS
Randomizer Ver. 4_6_0

Issue: When I try to save the ROM through LayeredFS it ends up saying Thread 5 Requested array size exceeds VN limit
before that it was thread 5 heap size which I fixed that with mine being -Xmx30828M
I dont't know what to do about the issue with array size.

Exception in thread "Thread-5" java.lang.OutOfMemoryError: Requested array size exceeds VM limit
