What were you trying to do that didn't work?
Hotplug virtio disk with aio=io_uring, then execute block_resize on the disk.

qemu crash on  qemu-kvm: ../block/io_uring.c:218: void luring_process_completions(LuringState *): Assertion `luringcb->co->ctx == s->aio_context' failed

3. hotplug disk with aio=io_uring

{"execute": "blockdev-add", "arguments": {"node-name": "file_stg0", "driver": "file", "auto-read-only": true, "discard": "unmap", "aio": "io_uring", "filename": "/home/kvm_autotest_root/images/storage0.qcow2", "cache": {"direct": true, "no-flush": false}}, "id": "hul0bYT2"}
{"execute": "blockdev-add", "arguments": {"node-name": "drive_stg0", "driver": "qcow2", "read-only": false, "cache": {"direct": true, "no-flush": false}, "file": "file_stg0"}, "id": "De38S5OW"}
{"execute": "device_add", "arguments": {"driver": "virtio-blk-pci", "id": "stg0", "drive": "drive_stg0", "write-cache": "on", "serial": "TARGET_DISK0", "bus": "pcie_extra_root_port_0", "addr": "0x0"}, "id": "niQrUGeT"}  Expected results

4. execute block_resize on disk
{"execute": "block_resize", "arguments": {"node-name": "drive_stg0", "size": 16106127360}, "id": "BskGR36w"}

Actual results
qemu crash  

PS: 
not hit the issue on
qemu-kvm-8.2.0-11.el9_4.x86_64

not hit issue when hotplug disk with aio=threads
