Custom fonts have stopped working?

HI guys,
I have been building a small app in bubble for a couple of weeks. Basically building something while also learning the ropes. I was a ta really good point and had my little app looking great, i just logged in with a new laptop (dont think this could have anything to do with the problems since its online) but all of a sudden my custom fonts have all stopped working.

Does anyone know why this might have happened and is there a way to retify it without going through the process of creating the files all again and doing all the uploading?

I have even just recreated one of the files and its gives the same error

This has been solved in the short term deleted all of them and started again still dont understand why they all stopped working.
