When I run almost any app on android studio, my logcat gets full of messages like:
\"? E/GnssHAL_GnssInterface: gnssSvStatusCb: a: input svInfo.flags is 8 ? E/GnssHAL_Gn
Not likely anything wrong with your app. The problem is probably the settings in the "Filter Configuration" in Logcat. It kinda hides as a setting, and has a habit of automatically switching to the "No Filters" selection. If you find out why, let me know.
To ignore the debug error in your question: in the Logcat panel choose a configure filter option in the drop-down after the filter input and Regex option checkbox.
Probably best option is "Show only selected application".
