As stated by DarkRyoshi and Kirisu, and a lot others.

Turning off SHADOWS in the config settings will fix "Any" on "Solo" mode. When attempting to find matches online.

Do not that this fix WILL work. But it will depend on the SERVER load. As stated by other users, the game can't handle around 60 players finding a match. So that'll cause it to crash.

For SEA players, I suggest playing in the Afternoon. GMT+8 around 12NN-6PM. Since the western server load is much lower during those times.
