Unable to unserialize on Sales -> Order page

Question

after upgrading the theme I can not access the sales -> order page any more with the following error. I disabled all third party extensions to solve possible conflict without success. I am using Magento 2.4

I'd appreciate any help. This is the error

It sounds like one of the entries in your ui_bookmark table contains a non JSON config value. You could try finding the culprit there by checking the entries for your user_id.

Alternatively you can empty the ui_bookmark table and see if that resolves the issue.
