[4.x]: Matrix Field can't save new fields

[kaspar-allenbach]

What happened?

Description

If I save a Matrix field twice, the new fields are gone.

I've migrated a craft 3 install to craft 4 some time ago and it is very janky.

I have a matrix field which at first glance lets me edit and add new fields. But if I go into the field settings a second time, all new fields are gone.

See here:

Steps to reproduce

1. Open the field settings of a matrix field
2. Create a new field
3. Save
4. Open the field again
5. The new field is gone

• No error shows up in the logs
• It seems to be only happening in these three fieldtypes GIPHY Youtube Video

When I check craft_matrixblocktypes in the db these fields have a fieldLayoutId value of NULL. Does this have anything to do with it?

Craft CMS version

4.4.3

PHP version

Sure seems like it.

What types of fields are these? What plugin is providing them?

[kaspar-allenbach]

These are just the text and the regular standard url fields within a matrix field. No plugins involved

Do you have any custom plugins/modules installed that could be interfering with the field saves?

[kaspar-allenbach]

I tried it directely on the production server and it's the same behaviour

There is a second filed in ieach block type. A Supertable field. Maybe this is affecting it. idk

Are you able to send your database backup and Composer files into support@craftcms.com? If so we can look into it from there.
