Like everyone has been saying, this isn't a Vortex issue, it's a general Skyrim game issue. You might want to ask the moderators to move the topic.
The T-posing issue is most likely because you have HDT Physics Extension installed in your Special Edition game. HDT PE is for the Legendary Edition game. What you want is HDT SMP. So uninstall HDT Physics Extension, remove it, and install HDT SMP.
You also want to remove the Female Skeleton Replacer, it's clashing with XPMSSE Skeleton. Are you sure you have the correct version of XPMSSE? (It should say XP32 Maximum Skeleton Special Extended v4.80) Make sure it's this one. You also do not require Realistic Ragdolls and Force, it's included in XPMSSE, so remove that mod.
Remove the vanilla armors replacer mod, I suspect that's also for Legendary Edition.
Double check your version of FNIS (It should say Fores New Idles in Skyrim SE - FNIS SE - FNIS Behavior SE 7_6) Make sure it's this one. Make sure to run the Generate FNIS for Users exe before you run your game and that there are no errors or warnings reported.
Update Bodyslide and Outfit Studio, you have a very old version, it should be 5.4.2 from here. Caliente's Beautiful Bodies Enhancer was also recently updated to 1.6.2 so you should update that.
Do yourself a favour and don't play your game without the Unofficial Skyrim Special Edition Patch.
