Submitted forms are not visible anymore

Your software
My Mautic version is: 5.0.4
My PHP version is: 8.1
My Database type and version is: MariaDB, 10.6.17

Your problem
My problem is: the results of my forms are not visible anymore after updating from 5.0.1

These errors are showing in the log: no error messages in nginx or php logs, neither in mautic logs.

Steps I have tried to fix the problem: migrate, update a second time,

Would be lovely if someone could point me into the right direction to debug this .

Same problem if anybody have any solution please tell us!

Can you regenerate assets?

bin/console mautic:assets:generate

assets have been generated. Form results stay empty. When I fill out the form with a test, then only this test is visible.

In the database, there is a new table, with only one single entry, the test entry:

When I look into mau_form_submissions, I see that there have been much more submission for form 3, but there are referenced with submission_ids that got deleted somehow.

I will check my backups later, if the form results are still there.

I now had to go back to a backup from february 2024 to see the forms again. After re-importing the old backup, the form results are back.
I really wonder, what happened and I am sad to loose more and more trust into Mautic and updates of it.
