Hi and welcome to the forum.
Meshtastic changes the GPS to run in UBX mode. The other SW needs NMEA mode.
@eriktheV-king has made a small program to reset the mode for the GPS. It is described in this post

Gps does not work in my application after installing Mestastic

Hello I’ve modified a LilyGO sketch with SparkFun libraries to help you out to reset U-blox NEO GPS devices on TTGO T-beam T22- V1.0 and 1.1 This sketch will bring back U-blox GPS N6M & N8M factory settings so that NMEA 9600 over the GPS serial output is enabled. You can download this sketch on my GitHub: It worked fine for my 5 T-beams… good luck !
