Instinct Solar 3 crashes randomly during activities

Hi,

since a few weeks my Instinct Solar 3 crashes sometimes during activities.

Last times it was while "biking" and yesterday while "walking" activity was used.

The err_log.bak showed me this:

Can someone tell me what is wrong and how to fix this? 

I have no courses on my watch, enough free memory (over 40mb) and no apps or watchfaces from the IQ store

Thanks a lot!
