Hi @Arkan_Afif, welcome to the forum.
The deformation is caused by a quantization of of vertex positions - an optimization that Shapespark applies to decrease the scene size. However, such a significant deformation might mean that the imported model scale is incorrect. What intermediate 3D format did you use to transfer the model to Shapespark, and what unit did you choose?
Also, could you upload the model to our hosting and share a link, so we could take a closer look?
