UE 4.22 and Maya: How to edit Maya´s grid to UE grid and Z axis the right way?

Hi, i tried to edit Mayas´s Z Axis up and Grid size to match it to Unreal, and this happened:

Now the grid is in vertical position and i canot navigate, because even do Maya´s Grid has perfect size and Z axis Up, grid is completly wrong and i canot rotate or navigate because its like if even do i changed the grid and Z Axis, everything else remains and i simply canot work like this, i cannot freely rotate with mouse and pan, nor open old projects and “corret” grid.

What can i do? … so frustrating.

Alt-Home I think
