Hi TDoro,
Go into your Projects content folder and remove the duplicated blueprint .uasset (don’t delete, just move it). Then try opening the project again.
:\Users\Yourname\Documents\Unreal Projects\YourProjectName\Content
If this doesn’t work or the issue pops up again after you recreated the asset; post your dxdiag, Log, and Dmp files. Also, post some screenshots showing that blueprints Event Graph and Components.
