Rescan Multilingual Tree - Error | Serialization of 'Closure' is not allowed | Core Version 8.5.4

I get the error
/updates/concrete5-8.5.4/concrete/src/Foundation/Processor/ProcessorQ Serialization of 'Closure' is not allowed (0)
when I click on Rescan Multilingual Tree.
I used the version 8.5.2 before.
I updated to version 8.5.4 and I am using php version 7.3.14.
Can you please help me?
The error ist still there!
Thank you
