Raid not starting, says “1 raider remaining” [Java]

So, I started a raid on my main base. Drank the bad omen 3 potion and no raiders spawned at the very beginning. The bar is indefinitely stuck on 1 raider remaining. I assume it’s a naturally spawning witch but I’ve checked all nearby caves that I know of and can’t find any. I rang the bell but it never highlighted any raiders, I even cranked up my render distance and nothing. Any ideas?
