I’ve been having this same issue, but mainly with pursuits or when having to chase someone on foot.
Just reinstalled GTA V to start playing again. Fresh lspdfr, no other plugins or addons.
After a pursuit or foot chase, when the suspect stops, usually after a taze, he just stands there with hands raised and I cannot interact. Other units depart and left standing there. Most recently was a pursuit that appeared while I was performing a traffic stop with callouts disabled. So I joined the pursuit, only to it be able to detain and arrest the suspect.
