TypeError: Cannot read property '_handlers' of undefined

Describe the bug

Been using this module for months now and it has been fine. But the past week my runs have sometimes run into a dump of

TypeError: Cannot read property '_handlers' of undefined

      at HandlerManager.checkMsgForLegacyHandlers (node_modules/steam-user/components/classes/HandlerManager.js:43:34)
      at HandlerManager.emit (node_modules/steam-user/components/classes/HandlerManager.js:29:8)
      at SteamUser.Object.<anonymous>.SteamUser._handleMessage (node_modules/steam-user/components/messages.js:612:24)
      at SteamUser.Object.<anonymous>.SteamUser._handleNetMessage (node_modules/steam-user/components/messages.js:533:7)
      at TCPConnection._readMessage (node_modules/steam-user/components/connection_protocols/tcp.js:194:13)

All errors are the same

Waiting a few minutes then running again sometimes fixes it. But i cannot tell if it is the way i am using the module (i am using the storage engine to store files in MongoDB GridFS buckets, in this scenario i am also logging on / off a lot), whether steam goes down or if there is actually an issue with the module.

Versions

^4.19.12

I am using the module here https://github.com/Kards-Stats/kards-tools/blob/main/kards/session.ts

The Error is being thrown when i run the tests (i am running live data in the tests, this is what i mean by im logging in / out a lot)
