Custom Rigged Rig not working as Expected when Imported to Studio

Hello,

I imported my custom rig into Roblox Studio, and everything seems to be set up correctly with bones, and I am able to edit the pose using the animation editor. The bones are in place, and the rig responds correctly in Studio. The problem starts when I try to import my FBX animation from Blender.

The animation does not play at all in Roblox Studio, even though there are no errors during import. If I take the exact same FBX animation file and import it back into Blender, it plays perfectly without any issues.

Does anyone know any solutions for this issue? I have attached several photos below demonstrating my issue. Any help is appreciated.
