Sorry about the issues you are having.
Please check your phone compatibility:
GoPro App requires Android 7 (tablets not supported)
360 requires Android 8.0+, with at least 4GB RAM.
Keep in mind that, particularly on Android, other factors present on the device can affect performance, even when recommended hardware requirements are met.
Also: know that the Team is working hard on 6.2.3 update which will bring many bug/crash fixes as well as improvements.
