Need help: Remeshing after rigging breaks animation link

Hey everyone,
I'm new to Blender and currently working on animating a character. I've already rigged it and everything was working fine. But now I want to remesh the character for better topology.

The problem is: after remeshing, the armature still has the animation, but the new mesh no longer follows the bones. I can see the rig moving, but the mesh stays still.

Is there a way to keep the mesh and rig linked after remeshing?

Thanks in advance for your help!
