Mine does same thing. 2020 Trail Boss. I do the force stop as well on running app screen and it starts working again. That definitely tells me it's a software issue. I been a technician for 30 years. Unless Chevy puts out an update or TSB the dealership won't find anything since it's very intermittent. I'll wait for an update but the force stop trick is so fast it doesn't bother me at all.
