It is likely caused by the lack of support for the AVX2 instruction set. For reference, see: TiDB 6.3.0 Release Notes | PingCAP 文档中心

If it’s a virtual machine, it is recommended to upgrade the image.

It really is this issue. The server model is a bit old and does not support AVX2. It is a physical machine. Thank you very much.
