IK and symmetrize option created this strange spike on the knee

[consummatumest]

I’ve removed the armature from the body, applied all tranforms to the body and set its parent with auto weights again but the issue still there

Did I miss any step?

[consummatumest]

okay now it works
I’ve applied all of the modifiers to the body and parented the armature after that

thank you so much

You are most welcome !
