So I logged in to my minecraft survival server, and went to my AFK raid farm, I got the bad omen effect, and the raid started, the bar got to full, and then stopped. no pillager sounds, no horn, nothing, it just stopped and did nothing, I have been using this raid farm for several weeks now with no issues before, is there any way to get rid of the raid and start a new one?

The only thing that I know might have caused it was my computer died and logged out of minecraft half way through the loading process, and as it is a server it keeps running even when nobody is on, when I got back on, the bar loaded the rest of the way, and then nothing happened...
