Process Explorer "run at logon" set in admin mode prevents user mode task tray icons

Windows 11 23H2 with all updates
Process Explorer 17.05 (64-bit)

At one point I had to launch ProcessExplorer in admin mode, and while in the instance I set "Start at logon".

Since then, it launches at startup but prevents the task tray icons from displaying in a non-admin login session, making the UI inaccessible.

To reproduce:

1. From a non-admin session run procexp64 as administrator
2. Enable Run at Logon
3. Close procexp64
4. Reboot

After that, on my system:

• procexp64 is running (as seen in Task Manager)
• Process Explorer tray icons are missing
• Since I have "Allow only one instance" enabled, I cannot launch another instance
• The only solution is to kill the running instance (the admin one) and relaunch
