PS I love how whenever anyone comments on US gun culture their comment guts downvoted to oblivion lol.
So I was exaggerating a bit. Obviously, mass shootings aren't "literally" not a problem in other countries; they're just so much rarer than in the US that the difference is, uh, striking. And you don't have them every single week, but they're common enough to make most of the world do a double-take.

Lewiston shootings, 2023 (19 killed). Last time something that big happened in the UK was the Cumbria shootings in 2010 (13 people killed). Before that, the infamous Dunblane Massacre in 1996 (18 killed).

Anyway here's where you're at:
You can't/won't give up guns coz of the 2nd Amendment so that's not an easy option.
You won't regulate them more stringently because too many Americans don't believe in that (even though you could introduce at least stronger controls without violating the Constitution).
So the way I see it you basically have the following options:
1. Change nothing, and just accept that regular mass shootings and assassinations are part and parcel of living in a free country, and it's just something you have to live with and pray you or anyone you know is not the next unfortunate victim.
2. Keep the rules the same so the vast majority of law-abiding citizens still get to enjoy their guns, just like they enjoy their cars despite a minority having accidents or driving under the influence, etc, but put huge effort into public education and teaching responsible gun ownership (reduces gun accidents), boost funding for mental health and trauma services (may help cut suicide as well as homicide to a lesser extent), address wealth inequality/poverty, and try and shift your sociopolitical narrative to be less polarized so you dial down the heat a bit along with hate for other people who don't share your views (as in, goes both ways). Along with maybe community violence intervention, stepping up police patrols on hotspot areas and focussed deterrence programs.
But personally I think that's a lot of work and it would be much simpler to just regulate guns more like Canada has done, at the very least for the more lethal ones like semi-automatic weapons. Up to you, I suppose.
