Pimcore 6.5.1: cannot save snippet

I just trying to save snippet and get following issue:

Status: 500 | Internal Server Error
URL: /admin/snippet/save?task=publish
Method: PUT
Message: The class “ContainerWihgNfi\appAppKernelProdContainer” is not cloneable.

Does someone met this issue?

Thanks for any help.

Check the logs of pimcore installation var/log

seems related https://github.com/pimcore/pimcore/issues/5866 and also see https://github.com/pimcore/pimcore/pull/5883. so it was fixed in version 6.5.2
