Error after the last WP Update.

I am having a bit of a problem with Your plugin, after the latest wordpress update on my website:
The problem is a “There has been a critical error on your website. Please check your site admin email inbox for instructions.” error message on the wp-admin posts page.

After some debugging I tracked it down to you plugin and found the following error in the log.

[08-Dec-2020 12:42:04 UTC] PHP Notice:  unserialize(): Error at offset 1779 of 2988 bytes in /home/digitalcitizen/public_html/wp-content/plugins/admin-columns-pro/admin-columns/classes/ListScreenRepository/Database.php on line 217

Can you please help me?
Thank you!

PS: My website runs on WP 5.5.3 and ACP is the latest version.

Hi there,

Did you get this issue after updating WordPress or after updating our plugin?
I do not hope that this issue is triggered by a WordPress update.
Technically this issue can occur when the data in our table ‘{prefix}_admin_columns’ is for some reason corrupt.
Can you maybe send me an export of that database table at
