Godot version

3.5.2

Issue description

Calling Crypto().generate_random_bytes() causes the engine to crash. Project compiles as expected but crashes when run. The same works with Godot 4.x (godot-cpp 4.0.2 7fb46e9ea1571b1364ab049b2088e9b302ff7985).

No helpful error message besides the following.

Solved using the following for Godot 3.x.

Crypto::_new()->generate_random_bytes(n)

Differs just slightly from Godot 4.x syntax as follows.

Crypto().generate_random_bytes(n)
