Immersive Horses is only half-functional; please help.

I've been using a new character to test Immersive Horses as a possible replacement for Convenient Horses, and so far it's simply not working right for me. When I try to open the Horse Menu or give ownership rights to a follower, I keep getting the message that "I need a horse to do that", even though I've definitely bought a horse and, as far as the mod is concerned, established it as mine. I'm hoping this is just a mod conflict, but so far I haven't been able to narrow down which is causing the problem. I've set my load order to have Immersive Horses load as close to last as possible to give it priority, but that isn't helping. Here is my current order:

 

*Unofficial Skyrim Special Edition Patch.esp
*SkyUI_SE.esp
*mjhSkyforgeWolfArmor.esp
*SimplyFasterArrows.esp
*Run For Your Lives.esp
*NARC SE for Vanilla.esp
*Dragonborn Delayed - After Horn Of Jurgen Windcaller.esp
*CompleteSkyforgeWeaponSet.esp
*icepenguinworldmapclassic.esp
*PyP_Legendary.esp
*BloodmoonRising.esp
*Predator Vision.esp
*skyforgedShields.esp
*skyforgedWeapons.esp
*AcquisitiveSoulGemMultithreaded.esp
*thatsracist.esp
*Immersive Horses.esp
*NARC SE patch - Immersive Horses.esp
*Modern Brawl Bug Fix.esp

 

Also, for what it's worth, I've got Skyrim updated to 1.5.50, and SKSE to 2.08. I've also installed the latest update of PapyrusUtil.

 

Someone please help. I've been reading mod descriptions for more than a week, and I've even gone as far as sending the mod author a PM about this (no response), but I still haven't gotten an answer on this. At this point, I'm very frustrated with this mod, and I'm about to just give up on it and go back to Convenient Horses instead.

As a quick followup, I've played around with the load order a bunch, moving Immersive Horses up and down the list, and nothing changes. I've even deactivated all the other mods and tried reloading my save with just Immersive Horses active, and that didn't help either. I'm becoming more and more convinced that this isn't a mod conflict, and there's just a problem with Immersive Horses itself.

 

Does anyone have any idea what could be going on?

Followup #2: Other people are starting to report similar problems. It seems the issues started after the latest game update was pushed out. Is anyone else here having these problems?

Followup #3: It's pretty clear to me now that Immersive Horses is simply broken. Posts on the mod's page are starting to report even worse problems than I've been having. It could be that the last couple of Skyrim updates pushed through Steam have left Immersive Horses incompatible, but that's just speculation. Whatever the reason, Immersive Horses simply doesn't work.
