So from what I know, and experienced. There is no reason to have Ultimate Backup, STP, Traffic Policer, and Smart Radio.
1. Smart Radio is outdated, even says it on the download page that only works with older versions of GTAV and I'm assuming LSPDFR. The last update for it was in 2019. In fact its been 2 years since its last update. So I'd start with removing that.
2. Traffic Policer is also out of date by almost 2 years, we're a month shy of that. Last update for it was in June, 2019. You shouldn't be even using those mods when you have Stop The Ped, and Ultimate Backup. Remove TP, and SR. Get back to me with if the game is still crashing. Also, I seen you called on the Coroner Van and there was no model to be found for it, that can also cause a crash. Make sure to check the .ini files and see if its set up to call on the right model, or if the model you're using is corrupt.
Lastly, doing the above should solve your issues. However, if it doesn't post a new RPH Log after you've done the above, and I'll take a look again and see if its something else, but from what I know, and again have experienced, Its due to you having x2 outdated mods, by 2 years that are no longer updated nor supported, and you have a corrupt model of some sort for the Coroner Van.
