Issue:
When using a 7+3 or 10+6 set, restarting the SlimeVR-Server app while the trackers are on and connected causes the majority of the trackers to get stuck at "connection to server". Turning the "stuck" trackers OFF does not solve the issue as they will boot again in that "stuck" state. The only solution to get them unstuck is to turn off ALL trackers, close and reopen SlimeVr-Server and turn the trackers on again.

Possible mitigation of the issue:
SlimeVR-Server could minimize to tray on "close" of the app so that trackers can keep communicating with the server. Shut down of the app should only be by right-clicking on the tray icon of SlimeVR-Server and selecting "exit". By applying this change the issue is mitigated as shut down of the server cannot happen by mistake.
See https://github.com/SlimeVR/SlimeVR-Server/issues/864

Recreation steps:
Using a 7+3 or 10+6 set

Open SlimeVR-Server
Turn on and connect all trackers
Close SlimeVR-Server
Open SlimeVR-Server

At this stage App will show only a limited number of trackers connected. All trackers that are not connected will have the status LED blinking with a single really short blink at a few seconds interval
Restarting the problematic trackers will not fix the issue as they will fail to connect again
Connecing the problematic trackers via USB will fail at connecting saying "Cannot connect to SlimeVR server"
