Thanks for the heads up HB_, taking a look at the error I was able to open my profile with vscode and I saw that my "rating" for the flea market was literally "Null" I changed it to my previous rating and my profile is working again
Coincidentally, I had the same problem yesterday and managed to solve it in the same way, luckily it was an easy solution.
Now I saw your comment and went to see if you had managed to solve it.
