Server.exe Crash:


Just wanted to share my crash/error log to see if anybody had this issue before:

2021.07.07-21.20.54:821][  0]LogWindows: Windows GetLastError: The operation completed successfully. (0)
[2021.07.07-21.21.10:127][  0]LogWindows: Error: === Critical error: ===

[2021.07.07-21.21.10:131][  0]LogWindows: Error: AnimSequence /Game/Customization_Girl/Animations/Walk_Anim.Walk_Anim: Serial size mismatch: Got 16046, Expected 16070

This didnt happen in UE4.23, which was my previous version. After updating to 4.26, everything works exceptional in the UE editor, including launching the testing there (with dedi server). However, when I compile the game (client/server) and I try to execute the server, after few loading lines this error comes up and crashes/closes the server.exe

I repeat, this did not happen in 4.23 prior to the update, and no, I have not modified anything regarding that animation. If I remove the animation from the project, another animation will show up with the error, hence crashing.

Things I’ve tried:

  1. Replacing the anim with a default one: same crash
  2. Removing the “WithEditor” function from the whole project: same crash
  3. Fixing redirectors and validating assets: same crash

I even pulled a backup (4.23) and built the client/server and has no issues.

I’m starting to think this is an engine error.
