An unexpected error occurred during tML startup
So I cannot start TModLoader at all, even though Terraria works just fine. I use the steam version of tml. I run it on a Windows 11 machine. I tried reinstalling Visual C++ 2015, deleting the folder, reinstalling, reinstalling all the dll files, updating nvidia drivers, everything i could.
Does anyone know how do i fix? 
Thank you guys for your help! :) ...

Resource Pack not working (Github Version)
I'm trying to install a resprite of Queen Bee and the Resource pack isn't working
Tmodloader won't update to latest stable release
I've been on the stable branch for a while, and today I saw that there was a stable release this month, however my version is still 2023.12.3.1.
When I was looking at various pages to see if I needed to do something to update my version, I saw that on the official github, the latest stable release listed is still the same version as it is for me currently, being 2023.12.3.1.
Is there something I need to do to update tmodloader to the latest stable release?
I'm using the steam version of both terraria and tmodloader on steam deck....
Creating Texture Packs for Mods
Is it possible to create a texture pack that replaces the textures of an installed mod? I'm trying to replace a texture from calamity infernum, so I downloaded it, unpacked it and found the texture I was looking for (it was in Content/Items/Misc). I created a resource pack, copied a slightly modified texture to the path ResourcePackName/Content/Items/Misc and ResourcePackName/Content/Images/Items/Misc but neither ended up working.
Is this currently supported, and if so, what am I doing wrong?...
Summoner Items not working
To be more specific, no matter what i do or how many minion slots i have available, all summoned minions despawn INSTANTLY right after summoning them, pretty much a milisecond thing, i use the summoning item, in that very second, the minion in question spawns and despawns, Sentries however seem to be working perfectly fine, at first i thought this was a problem with Calamity, but all summons including vanilla are affected, so i thought of asking here first, mod list is a bit long so i'll post it...
(fixed)
So I'm trying to play with my friend, however anytime they join, it doesn't want to load calamity music, I'm the one hosting the world, we both have same mods downloaded, regardless of my friend not needing them. Any help is appreciate

Lost progress
Yesterday I was hosting a multiplayer server with a friend via Steam.
Today I opened the game to find my player and world progress be restored to an earlier stage.
I have checked my 
C:\Users\%USERNAME%\Documents\My Games\Terraria\tModLoader folder to find existing backups of both player/world that seem to have little more progress, but still not on part to what I had when closing the game.
