Random GPS failure message on boot

[jaroszmm]

Sometimes, when I power up my plane with INAV 7 or 8 RC2 (tried on both) I get long constant beeping and GPS Failure message on OSD.
Sometimes GPS will connect after a short while, sometimes after a longer time. Sometimes it needs rebooting. Today however it wouldn't connect at all at the field and bench on 8 RC2.

I had to go into configurator, in PORTS disable GPS as sensor, reboot, go again into PORTS, enable GPS as sensor again, reboot - GPS works fine.

GPS is a solid BE250 module I've had for quite some time now. I also notice this on some other builds that sometimes INAV takes a longer while to actually communicate and realise that there is a GPS connected to the FC.

FC is Matek F405WMN on either 7.1.2 Stable or 8 RC2
