The writer portal's preview section is not working

Can anyone tell me how to fix this problem please?
I saw someone said use Chrome would help so I did, but it’s still now working.
The preview has a bunch of number and under the numbers i.s blank.

this same thing is happening when I try to edit my charactera and write :frowning:

Same! The previewer works on my Yoga laptop, but it doesn’t work on my other one. Sadly, my yoga doesn’t work anymore, soooooo :sob:
