FAB website error "Sorry, we couldn’t find that page." es-es/es-es bug

Summary

If I am not signed in or incognito mode and enter this URL https://www.fab.com it will work.

But when I sign in and enter this https://www.fab.com, it will not work and the URL auto becomes https://www.fab.com/es-es/es-es/ and says ‘Sorry, we couldn’t find that page.’ with a ‘take me home’ button, but even when I press the ‘take me home’ button I end up on the same error page.

Additional Notes

solutions I tried:

This is happening on both brave browser and Microsoft edge, as soon as I sign in.

clean out cache but same issue as soon as I sign in.

tried on different device like my Iphone and same issue as soon as i sign in.

some say I have to change the language setting but now, I am forever stuck on this page.

if random input URL https://www.fab.com/asdfsadfa it doesn’t add the /es-es/es-es/ and still takes me to the ‘Sorry, we couldn’t find that page.’

But if i input something legit like https://www.fab.com/sellers/FreshCan it will add the /es-es/es-es/ and the URL will come out like https://www.fab.com/es-es/es-es/sellers/freshcan and still takes me to the ‘Sorry, we couldn’t find that page.’
