The editor crashes when creating a local collection of the same name by typing certain characters in the search box of the content browser. This does not reproduce in UE5.4 and is a regression in UE5.5.
This case is similar to [Link Removed].
1. Type "x1" in the search field of the content browser.
2. Create a collection pressing the "+" button on the right under "Local Collections"
3. Rename the created collection to "x1"
Result:
Crash in the editor.
Epxcted:
No crash occur.
