The Zoom Crash fix only works when the ProMods map background is active and below it in the loading order.

It's because you need the ProMods Map Background (https://steamcommunity.com/sharedfiles/ ... 2485894487) and the Zoom crash fix (https://steamcommunity.com/sharedfiles/ ... 2701258039).
Put these both files above all ProMods,files, and the Zoom crash fix above PM Background map.

1) Please download the zoom crash fix and place it just above the ProMods Complete Afroeurasia background map : https://steamcommunity.com/sharedfiles/filedetails/?id=2701258039 2) ProMods DLC Support should be above ProMods on the load order. 3) Google Maps Navigation ProMods Addon should be above ...

You're welcome, Merry Christmas to you too.

You need to load one of the ProMods background map, and put it just bellow the zoom crash fix on the load order.
Zoom crash fix didn't work without a background map.

Please post your game.log here, with pastebin.com.
