Symfony recipe update conflict resolution fails with phpstorm

[Tib-z]

When using PhpStorm v2024.*, running certain Symfony Flex recipe updates (e.g., composer recipes:update doctrine/doctrine-bundle) causes conflict resolution to fail. The following error is displayed in PhpStorm:

Error loading revisions to merge: cannot read object [Hash] '[File path]'

A bug report has already been submitted to the JetBrains issue tracker (IJPL-158448). However according to JetBrains staff, the error is triggered by a missing blob, potentially linked to the Symfony recipe repository or the update process itself.

I haven't investigated Symfony Flex internals or debugged the issue deeply, so I cannot determine whether this is a problem with Symfony Flex's handling of files during recipe updates or a bug in PhpStorm.

Steps to Reproduce (also refer to the jetbrains ticket for repro):

• Use PhpStorm v2024.* with a Symfony project.
• Run composer recipes:update doctrine/doctrine-bundle (or a similar recipe update).
• Attempt to resolve conflicts through PhpStorm.
• Observe the error: Error loading revisions to merge.

Expected Behavior:
Conflict resolution should work seamlessly after recipe updates without errors.

Actual Behavior:
Conflict resolution fails, displaying an error about being unable to read an object or file.

I can confirm this. It did happen only on symfony/asset-mapper.
This was the first one i picked to update.

@Tib-z Did it happen on all recipes or just the first one?

As far as I remember for me it happend with doctrine/doctrine-bundle and symfony/twig-bundle (not with the first one update).
