[4.19.2] After hotfix upgrade Unreal editor crashes on load with plugin errors. Unable to load project files

Hey,

I recently upgraded to the 4.19.2 hotfix but now my project no longer loads.

I get a range of missing plugin errors when I open my project (I’ve tested with two 4.19 projects, both with the same results).

"The error message is “binaries for the plugins are missing or incompatible with the current engine version. Would you like to disable it? You will no longer be able to open the assets”

The dialogue box popups for these plugins:

  • CharacterAI
  • HTML5Networking
  • AndroidMedia
  • AvfMedia
  • Imgmedia
  • LinearTimecode
  • MediaCompositing
  • MediaPlayerEditor
  • WmfMedia
  • TcpMessaging
  • UdpMessaging
  • ActorSEquence
  • LevelSequenceEditor
  • matineeToLevelSequence
  • NetcodeunitTest
  • NUTUnrealEngine4

I gave no to all these dialogue boxes, but then a final dialogue box which says the following kills the app altogether.

I tried creating a new blank project, but although this doesn’t get the plugin errors, it does crash with the previous error message.

I only started having these issues after upgrading to 4.19.2 hotfix.

Is someone able to assist? I really need to get this back up and running as soon as possible.

Cheers,
Krish.

If I disable these plugins then unreal loads, but all my sequences are empty. I presume critical functionality has been removed since I disabled them. I could really use some assistance.

i have upgraded engine many times for both Bp and C++ projects. which one are you working on?

BTW you must first upgrade your plugins in your project folder. those plugins which are in engine folder are upgraded by launcher when you download a new version of engine

Thanks for your reply Saeedc. I upgraded to 4.19.2 via the Game Launcher. None of my plugins in the ‘Vault’ section in my Epic Game Launcher is showing as needing an update. Also, the plugins which are having the issue are Epic plugins which I thought would be updated as part of the engine update via the launcher?

Okay, I’ve resolved this. I reinstalled the entire engine via the launcher and its now working.
