Backup or restore with twrp breaks gps

I'm using xiaomi mi mix2s (polaris). The rom is xiaomi.eu_multi_MIMix2S_V11.0.3.0.PDGCNXM_v11-9.zip. twrp uses twrp-3.4.0-0-polaris.img. I have installed the gnss logger app to improve the accuracy of gps. I'm playing a game using gps. However, when I get a backup (boot, system, data, efs) with twrp, gps becomes unresponsive and gnss logger does not start. When gnss logger does not start, you will not be able to use the gps game. Restoring from backup does not improve. If you initialize the mobile device, gps will be restored, but if you restore from there, gps will stop responding again. I don't know if eu rom and twrp are incompatible or if twrp-3.4.0-0-polaris.img is broken. So I can't perform a backup or restore. Which rom does twrp-3.4.0-0-polaris.img work with? Is there a way to restore the gps function?
