Editor Camera seems to be bugged

When I loaded up my project today I opened up an actor blueprint and went to the viewport as shown

However, upon clicking on the object, the camera seems to change the FOV. As shown below.

Does anyone know what may have caused and if so is there a solution or is it a bug with 4.22.3?
Thanks in advance.

A restart of my computer seems to have fixed the issue. Loaded up the project the next day and is now fine.
