Came back, but i lost my character

Hi, I restarted playing wow on Warmane during lockdown two years ago. I leveled up a human warrior (lvl 20-30) with the x1 xp rate with friends, then we stopped with the end of the lockdown. I recently reinstalled the game, found my password miracurously but I think I've lost my character (I still have a 80 rogue on the PvP only, but my warrior disappeared, and I have the (1) beside the realm saying I created a character on this realm but it's not there)). Do you know about this ? Is there a way to retrieve my character ?
Thank you guys

Most likely an inactivity cleanup - Check this post https://forum.warmane.com/showthread.php?t=443191

Oh ok. But is there any chance i can get a new lvl 30 character ? (if i can't get mine back)
