How to change compatibility options?

Hi, I’m making a map for a game called CARRION. I’m currently using Tiled 1.9.2 to do this. (I was using Tiled 1.3.5 to make maps before.) I’ve recently come across an issue - When I launch up the game and try to enter the level, the game crashes. I’ve reached out on to other people about this. Bjorn told me it was a compatibility issue and that I could change the compatibility settings for a fix. One issue - I can’t find the option to change said setting. Anyone know where it is?

P.S. sorry for the long paragraph

It will be in your Project Properties (Project > Project Properties). You will need to have a project loaded to be able to change its properties, so if you don’t already have a project, you may need to create one.
