System Error calling Storage.setValue() lastest FW

This bug report evolved from https://forums.garmin.com/developer/connect-iq/f/discussion/383923/system-error-calling-storage-setvalue-lastest-fw-on-venu-3-and-fr-965

I'm getting many user reports of watchface crashes. if I look in ERA these are System Errors when doing Storage.setValue(). This is happening since the latest firmware on Venu 3, FR965, FR265. Some reported other devices as well.

Quite an annoying bug, as restarting the device sometimes works, but some users reported the error is appearing again after a while.
