What happened ?

When creating an HID with CH32V203 and sending a report of random numbers as a test, a HardFault will occur after as little as a few seconds, or as long as a few tens of minutes.
The call stack is often displayed as shown below, but sometimes only up to tud_task is displayed, or the call stack cannot be obtained at all.

HardFault_Handler@0x00000794 (ch32v203_tinyusb_hid_test\src\main.c:16)
osal_queue_receive@0x00001c42 (ch32v203_tinyusb_hid_test\src\tinyusb\osal\osal_none.h:166)
tud_task_ext@0x00001c42 (ch32v203_tinyusb_hid_test\src\tinyusb\device\usbd.c:577)
tud_task@0x000008fe (ch32v203_tinyusb_hid_test\src\tinyusb\device\usbd.h:57)
main@0x000008fe (ch32v203_tinyusb_hid_test\src\main.c:89)

I tried it with two chips at first, and both ended up in the same situation.
The error also occurs when the contents of the report are changed from random numbers to incrementing them each time a report is sent, but if the same content is continuously reported, it will almost never occur regardless of the value.

How to reproduce ?
