Playfab Plugin for Unreal Engine Freezes HTML5 Game

Hello, I am really in need of help.

So I am currently working on a game that needs to be playable on a webpage, (preferably HTML5)
therefor I am having to use Unreal Engine 4.23 as it was the last version that supported
packaging for HTML5.

Azure will be the service my client uses, and thankfully the Playfab plugin for Unreal supports this older version.

So I have been learning lately and everything has been going great, except I have now discovered that when packaged as a shipping build for HTML5,
the game freezes the moment a Playfab blueprint node is reached and executed.
This includes even just setting a JSON Object variable with the "construct json object" node.

It works perfectly fine when packaged for windows and in the editor itself, but not when testing on a webpage :(

Any help would be greatly appreciated as I am quite stuck.

Is there any error message returned by your game? If there is, could you please provide the detailed error for our reference?

I'm afraid not. Or at least, I don't know what I could do to discover the error.

Since the issue only happens once the game is running on a webpage, I'm not sure if there is any way to see an error log when it freezes.

Apologies for the delayed response. For the HTML5 game, you can hit the "F12" key to check the console that provided by the browser, so that you can check the output message of the game.
