topdown rendering order [Solved]

Hi every one my problem seem to be tough one since every thing was fine until I updated unity from 2020.2.7f1 to 2020.3.18f1 lts version.
my game is top down style and after updating unity, it seems that the grid system doesnt render properly and also sometimes has some interferes with sprites.
any way as you can see in the picture it is now what unity shows

and what it it used to show before updating unity

exept the weopn should be behind the wall and i dont know why !!

by the way all settings are fine and was working properly before update

Well i wonder why some setting changes wierdly after updating unity…
Any how i just has to change transparency sort mode in 2d renderer data file to custom axis and change y to 1 and z to 0
