Prefabs not deleted from memory during self-destruction

Describe the bug
Prefabs (extension objects) are not eliminated from memory during self-destruction.

That is: I want an object to destroy/elimiate itself when a condition is met (eg. certan time has passed). However when this action is set from inside the object, or the extension, the object is not removed from memory.

Notes: I have the latest update of Win 11 and GDevelop. I have seen this issue in an ongoing project and a completely empity fresh project that only replicates the bug.

The prefab object:

Before the condition is met:

After the condition is met, the sprite is deleted but the instance and all the memory remains:

Share the complete GDevelop project showing the bug
I tried to upload to http://drop.devloprog.org/ as suggested, but the page wont open. Also, thie forum only allows for images. If needed, I can share the example at anytime. I have asked about this vefore in the Discord chat and the forum without a glimpse of an answer, so I guess this is, indeed, a bug.
