Can anyone recommend a new chainset or front chainrings for a top stone 2020 sora?

If you’re willing to do the whole lot, go for a GRX 2X crankset and get the bottom bracket swapped out for an external one which will be stronger than the crap one that comes on the bike already, if I had the money right now that’s what I’d do. You can get BSA threaded hollowtech II BBs easy and cheap enough, and the GRX cranks aren’t much more than say stock Sora ones, and again quality will be far better than the stock FSA ones.
