Repenting when sun rises from the west

Hi so im a revert and I just read that you can’t repent once the sun rises from the west. But I’m wondering, does that mean that if we commit sins after that we can’t repent? Or does that just mean the disbelievers? What would happen if I accidentally commit shirk/kufr after that sign, can I not ask for forgiveness anymore? I don’t know how to interpret it and it really scares me now.
