Recently on my 2019 MBP running Sonoma 14.4.1 I notice that the UARPUpdaterServiceUSBPD daemon grows slowly but steadily, eventually taking up multiple GB of memory. I don't know how to determine whether this is due to 3Dconnexion driver 10.8.4 or from something else. I have a fairly old USB-connected Space Navigator. It is working fine with this driver installed. But it is a pain having to reboot every few days to knock this hog back down.
Has anyone else observed this? Is there any way to tell what is causing the memory growth (I really don't understand what this daemon is supposed to do and can't believe it really needs so much memory unless it is a bug in Sonoma or some USB device is triggering it)?

Follow up: I contacted Apple support. They spent quite a bit of time with me, but in the end to no avail. The support reps had never even heard of thie UARPUpdaterServiceUSBPD daemon and had no clue what it does or how to diagnose the cause of the memory leak, even though it is an Apple facility that is included with macOS!

@slbaumgartner, I see that you have also contributed in the relevant Apple's community forum here.
We do not have any information on UARPUpdaterServiceUSBPD. Until you reported this, I was not even aware this daemon existed.

Re: UARPUpdaterServiceUSBPD memory leak?
I have since discovered that this issue appears to be governed by which USB-C port I use to connect the charger cable to my 2019 Intel Mac Book Pro. If I use the right rear port, the issue appears. If I use the right front port, it does not happen. As a result, I doubt that the Space Mouse driver is involved.
