GD32F407VET6: JLink debugging faults after 30 seconds

Title edited - part number added (not an ST part)

After commencing debugging with the JLink, these faults persistently occur after approximately 30 seconds. However, this JLink functions correctly when debugging IAR. What might be the cause?

The actual chip used is the STM32F407VET6.

JLink keeps disconnecting from CubeIDE for some reason. Debugging frequency SWD=500k

If, as shown in your schematics, the GD32F407VET6 is used, you should ask its manufacturer Gigadevice.
