Using the latest C# driver version (2.13.1) and latest MongoDB community server version (5.0.2).
Trying to use where in projection yields an incorrect query (besides the already reported issue from CSHARP-3783 GroupJoin with projection yields incorrect query - MongoDB Jira).
In the example below showing how the driver translated c.Where(ch => ch.ParentLevel == p.Level).All(ch => ch.Status == p.Status), you can see it effectively translated into c.All(ch => ch.ParentLevel == p.Level && ch => ch.Status == p.Status) which is not equivalent logic.
ChildrenConsistent = (c.Any(ch => ch.ParentLevel == p.Level) || p.Status == SerialStatus.Destroyed) && c.Where(ch => ch.ParentLevel == p.Level).All(ch => ch.Status == p.Status)
{
