Overpowered characters can work, as long as you have plots that don't rely entirely on fighting, and its merely a tool that they can use for some situations and not every situation. Overlord is a good example of this. Ainz could probably single-handedly conquer the entire world, but because he doesn't know if there is some other ultra-powerful enemy out there, he has to act cautiously. He is constantly dealing with things like politics and other things that can't be ideally solved with violence. It also focuses on other characters that aren't the overpowered protagonist, and they might face actual consequences.

Log Horizon is another good example, because it manages to make things interesting despite most of the characters being immortal.

Slime's protagonist might very briefly be inconvenienced, but they don't really ever struggle. If they ever face failure, a solution will soon fall into their laps to fix everything.
