Default password seeding not working properly

[LokenLaishram]

this is the default password seeding
if (userManager.Users.All(u => u.UserName != administrator.UserName))
{
await userManager.CreateAsync(administrator, "Password123!");
await userManager.AddToRolesAsync(administrator, new[] { administratorRole.Name });
await userManager.CreateAsync(demo, "Password123!");
await userManager.AddToRolesAsync(demo, new[] { userRole.Name });
}.
I found Invalid column name 'IsLive' Exception. How can fix the issue?
