This should not happen. Which kernel version are you using? There used to be a use-after-free on concurrent DPC and hot-removal. It was fixed by 11a1f4bc4736, which went into v6.11 and was subsequently ported all the way back to v5.10-stable. I suspect you may be using a kernel which lacks that fix. Thanks, Lukas
