Doesn't the herpes virus generally reactivate when the immune system is being run down?

I know there is literature to suggest that Cold Sore outbreaks in an individual generally occur during cold and flu outbreaks.

I'm pretty sure that's why they're called cold sores, and I've had them happen during flus before, although not during the vast majority of them. Nevertheless, I haven't ever had a situation like I got with covid, and the actual covid symptoms were minor (after the first day, which was a weird intense generalized weakness that eventually went away.)

Covid is a cold, anyway. A strong, strange cold.

My cold sores will break out after any sort of physical stress (excluding exercise). Ironically I get them most often after heat exhaustion.

Aren't most variants of cold and flu members of the corona-family of virus? If so, it would seem logical that COVID also being a coronavirus would have the same (or at least extremely similar) effect on cold sores as other members of the same viral "family" would cause.
