R15 on spawn has a abnormal rig

Hey I keep running into a issue where the character spawns in weirdly with a “broken” rig, theres no script that edits the character, all scripts are made by me so theres no sneaky scripts editing the character, (its not a pre made character, no StarterCharacter) it just spawns in with some randomized C0 CFrame values at the different body parts making the character abnormal with twisted and body parts completely moved away from the body, and I would like to know why this keeps happening and how I can prevent it, I have asked AI, specifically Claude trough a MCP server to go check it out, it cant identify the issue (and it actually says tell me if u find the bug)

Sometimes it can spawn in properly without any weird bugs, but it has happend way too many times now,

Respawning fixes the issue, but I cant have players reset their character on spawn


Expected behavior

I expect the character to behave as normal, no weird rig,

I have tried to “calm down” scripts at client launch (suspecting it might be too big of a load at the same time), such as using: repeat wait() until game:isLoaded(), tried disabling scripts, it has no effect, im making this bug report because I think this might be a issue at robloxs end

EDIT: oops I marked rblx studio not engine, this should be at engine category

EDIT 2: I found the fix, its the animation graph thing which is in Beta that makes the character glitch, making this a studio bug, so the category is not wrong
