@magge OK so....after a lot of testing I think I have narrowed the issue down to 2 mods. "Rings For All" and "UI mod tools"
The random freezing while zooming in and out would almost happen many times during an average game (even if it didnt completely freeze and crash) and that effect is nowhere present when those two mods are disabled and zero crashes now or anything for many dozens of games.
For my part I have no skills to investigate this further but it does seem like there are a lot of people complaining about mid game crashing so maybe this is related.
I am able to use my favorite icon packs again with zero issue, the only bummer for me is not having Rings For All active because that is an amazing mod but build range preview has been working fine so everything is back to normal in FAF world for me.
Thanks for steering me in the right direction.
If anyone else is crashing mid game and you have either of these 2 mods enabled try disabling them and reassessing.
