Force updating Label with cache mode CHAR gives error in DEBUG MODE

Hello all,
While using a label with cache mode CHAR and assigning empty string, then calling updateRenderData(true) gives error for failing assert in RenderData.updateRenderData in DEBUG mode in native.(web works fine)

Any help to fix this would be appreciated.

This might be a bug in CC3.8.3 since it was working fine in CC3.8.2.
