Hi, same issue happening to me. @talsan74, did you find out what was causing it?

[matiasgaletto]

Okay, as far as I have tested, the issue is caused by having the name of a category with a trailing empty space. Instead of "Category Name" it has to be "Category Name ". I haven't been able to reproduce the issue in version 2.4.6-p4 but I was able to do it in 2.4.7 and 2.4.7-p1. So anyone who updates to any of these versions will have this error, which cannot be fixed by a common user. It can only be fixed by making a SQL query to the database. If you check the Dev Tools Console and go to where the parsing error happens you can verify the issue.

Steps to reproduce:

1. Install Magento 2.4.7 or 2.4.7-p1
2. Add a category with a trailing space in the name. "Category Name "
3. Go to Admin Panel > Catalog > Category
4. Should stay loading forever.
5. Check Chrome Dev Tools Console, you should see an error message.
6. Click on the error and see in the file that the parsing error happens where the category name has a trailing space.

@engcom-Dash could you reopen this? A lot of people are going to have issues if not fixed soon.

@engcom-Dash Please consider extending your testcase and reopen this issue. I can confirm it is reproducible as mentioned by @matiasgaletto. An additional test case is when the category name has a carriage return symbol in it (\r). Yes, I know that it isn't supposed to be in a category name but neither should the whole page be broken because of a wrong character in the category name. Many merchants will be affected by this, especially those who get their data imported from a PIM and not added by hand in the admin area.

@engcom-Dash : I also think this needs to be reopened.

I have struggled with this issue for over a month now and by following the above information I was able to run the following query in phpmyadmin to find the problem category names

SELECT * FROM catalog_category_entity_varchar WHERE value LIKE '%\r\n';

Once I edited these to remove any new lines or white spaces on the end of the string the category list populated on the admin part of Magento straight away.
