I actually tried again yesterday and it just started working, im not completely sure how but I think because I had my computer fully turned off and then powered it on and immediately ran the emulator it was able to allocate the memory. Try turning off your pc fully like unplugged from the outlet and then immediately run emulator after turning back on, I think thats what did it for me but not 100% sure

Im not sure exactly why mine started working, it will most likely be fixed in the upcoming versions though.
