Skitour app crashes with out of memory (errnum 0x00f) while using ConnectIQ data field

On a Fenix 6x Pro, the Skitour app crashes on long skitouring activities (after several hours of recording) while using a ConnectIQ data field. It is not the data field that crashes, but the entire watch (resetting). The same does not occur with other activities (e.g. Hiking) when using the same ConnectIQ data field. 

Here is a copy of err_log.txt after the crash:
