      I've got a C# .NET application (driver 2.19.0) and I'm querying a DB using IAggregateFluent with a match, a lookup, and a projection. This is the pretty-print of the query - it's nothing terribly fancy:

      [
  {
    "$match": {
      "Timestamp": {
        "$gte": "ISODate(2023-02-20T14:40:00Z)"
      }
    }
  },
  {
    "$lookup": {
      "from": "RemoteCommandResults",
      "localField": "_id",
      "foreignField": "CommandId",
      "as": "Results"
    }
  },
  {
    "$project": {
      "_id": "$_id",
      "Command": "$Command",
      "CommandType": "$CommandType",
      "Timestamp": "$Timestamp",
      "ClientIpAddress": "$ClientIpAddress",
      "Location": "$Location",
      "SubmittedByUser": "$SubmittedByUser",
      "CompletedEndpoints": {
        "$map": {
          "input": {
            "$filter": {
              "input": "$Results",
              "as": "r",
              "cond": {
                "$ne": [
                  "$$r.WhenCompleted",
                  null
                ]
              }
            }
          },
          "as": "r",
          "in": "$$r.EndpointId"
        }
      },
      "PendingEndpoints": {
        "$map": {
          "input": {
            "$filter": {
              "input": "$Results",
              "as": "r",
              "cond": {
                "$not": {
                  "$ne": [
                    "$$r.WhenCompleted",
                    null
                  ]
                }
              }
            }
          },
          "as": "r",
          "in": "$$r.EndpointId"
        }
      }
    }
  }
]

      I'm using CSFLE with mongo_crypt_v1.dll and running on Windows.

      If I don't enable encryption, i.e., leave the AutoEncryptionOptions out of the MongoClientSettings, everything works as expected.

      If encryption is enabled however, either libmongocrypt.dll or mongo_crypt_v1.dll prints an assertion failure to the console window and aborts the application:

      {"t":{"$date":"2023-03-09T21:04:56.738Z"},"s":"F",  "c":"ASSERT",   "id":23079,   "ctx":"thread13","msg":"Invariant failure","attr":{"expr":"isVersionInitialized()","file":"Z:\\data\\mci\\badd693c2380d3476d7367abd345c3b9\\src\\src\\mongo/db/server_options.h","line":156}}
{"t":{"$date":"2023-03-09T21:04:56.738Z"},"s":"F",  "c":"ASSERT",   "id":23080,   "ctx":"thread13","msg":"\n\n***aborting after invariant() failure\n\n"}

      The query seems to be well formed, as evidenced by the fact that it works when the encryption libraries aren't in use, so I suspect there may be a bug in the encryption libraries and how they handle aggregation pipelines.
