Poll Block breaks skin

Hi, 

When I update PHP from 7.4 to 8.2 my skin fails due to my initialized Poll Block.

When I click on options for Poll in the Blocks admin area, I see this error message:

A fatal MySQL error was encountered.
Query: SELECT * FROM fanfiction_poll WHERE poll_end IS NULL OR poll_end = '0000-00-00 00:00:00' ORDER BY poll_id DESC LIMIT 1
Error: (1525) Incorrect DATETIME value: '0000-00-00 00:00:00'

Has anyone else experienced this problem or know how to fix it?

On the sidebar you can see "Ebook Poll" however there is no poll associated with the block anymore. 

I'd appreciate any all help.
