Products've gone after upgrade 2.4 from 2.3 in a NO MANAGE STOCK catalog

Hi all,

We are facing inventory problems with a Magento 2.4.3.-p1
We've upgraded from a Magento 2.3.3 in a NO MANAGE STOCK catalog. There are no transactions by now, no prices, etc. This works fine in 2.3 until now, products are appearing in fronts grids etc.
After upgrading to 2.4.3 all products have disappeared from frontend grids. Only the individual product view runs well.

First of all, we've noticed all inventory modules were disabled. In 2.3 this was not a problem.
After enabling them, the source and stock configuration have appeared in the stores inventory configuration. We've configured the default source with default stock just in case.

Elastic is running well and reindexes are done.Shall we need to enable inventory modules to work with no managed stock options? Are we missing anything?

Thanks in advance

Seems like you are having the same problem as me!

We've found an error in grid sorting on a custom attribute.
The log wasn't showing well the problem.
So, this malfunction does not related with a Magento bug or nothing about inventory.
The problem was something about that sort attribute and compatibility with 2.4.3 version.
