Wc3R crashes 1v1

Hi

I purchased and installed wc3R recently.
I tried to start a few games to see the game in action and get used to it.
Vs bots it works.
I also managed to play 2 games vs players.
However I got some crashes.
2x were without report

1x was with Retail Grafic, it gave this report:

The instruction at 0x00007FF7E57628C7 referencced memory at 0x0000000000000008. The memory could not be written.

1x was with Classic grafic:
Link: ibb . co / n0psVnB
(please copy paste and remove spaces then press Enter to see the error report)

I am using an 8GB laptop. But the memory is nowhere at max, and the minimum requirements are 4 GB, max are 8.

So… Why is there problems?
Do I really need more RAM for this? Again, as you can see in the Link, I had plenty of room.

What else of information do you need?
Thank you
