Packaging with restored blueprints does not work for me

Hello,
First sorry for my english.
I have a problem with packaging my project.
Three weeks ago my pc crashed because I had a blackout.
Some blueprints did not save correctly and the engine was unable to open them.
But I used the backups and all worked fine again.
Today I wanted to pack my poject because I wanted to test it in “WindowsNoEditor” modus, but I got the following erros:

Packaging Log

So it seemed to mee that the restored Blueprints are not working for the packaging.
I would very looking Forward to Hearing from you, if you know how I can fix this ;D

Hello ,

From looking at the errors, it seems like it’s only having issues with a few files. If you look through the log, you can see the names of the assets that is having trouble with. Some of them are simple, such as static meshes from the Starter Content pack. Could you look through and see if those items are in your Content Browser and that you can open them without any issues?

Heres an example of one of the errors:

Failed to load ‘/Game/Architecture/SM_Floor_400x400’: Can’t find file ‘/Game/Architecture/SM_Floor_400x400’

We haven’t heard from you in a while, . Have you had a chance to try what I suggested in my previous comment? If so, what were the results? In the meantime, I’ll be marking this issue as resolved for tracking purposes. Please comment here to reopen the post when you have time to work on this issue.
