Cannot Play Level when Pressing Play

Hello, I have just come across a problem that had not occurred before. When I want to play my level either in the Selected Viewport and/or as a Standalone Game, I cannot move my Character. W,A,S,D or any of the Controller Controls I have made do not work. The Scene also seems to be idle when moving Objects around the Scene and when attempting to Play. The Clouds in the Sky do not Rotate, nor do any of the Trees or Bushes even though they have Wind simulated upon them. I have double checked my Game Mode and any other Classes related to it but there are no errors. I’m very confused because everything was working fine yesterday.

This only occurs with this one Level. My other level is playable in full.

Can someone please help me, it will be much appreciated.

Thank You

Are there any errors in the message or Output logs?
Did you set a Game Mode override for that level that doesn’t use your usual PlayerController class and default Pawn class etc?

Hello, thank you for replying, Yes I have set a Game Mode override for the Level with the correct PC and Pawn Class.

There aren’t any Error Messages

Hmm I don’t know. How much effort would it be to recreate the Level in a different level? If all the others work maybe that will solve the problem if we can’t identify what’s going wrong.

It is quite a complex Level. But I can try and move it to another Level.

In your level blueprint, you don’t have any Loops that run on Tick, do you?

No I haven’t. Also I tried moving Level to another, and the same issues occur. I’m so confused.

Hmm me too. I thought maybe you had something in the blueprints that would slow it down a lot to make it look frozen.

I’ve just tried moving the Level to an existing Level that works and the issues have passed over to that Level. It used to work but now by moving the Level into it, its no longer working.

Okay then there might be a Blueprint class or other asset that you only used in the problematic level and not in the others, which causes the problem. Which asset or blueprint does not exist on any other level except that problematic one? The World Outliner lists all assets that are placed in the level before play starts.
