Overview

One reference in a note of an entry works fine.
Adding another reference in this note causes KeePassXC to crash:
"unknown software exception" (0x40000015) appeared at position 0x00007FFFD68D4F5.

Steps to Reproduce

Attached are 2 keepass DBs: "Ref1.kdbx" and "Ref2.kdbx" - no password.

1. Open "Ref1.kdbx"
2. Edit note of Ref1 / Bank / B1.

• It's note contains a reference to note Ref1 / Bank / C1: "{REF:N@I:ABD457C6174F7C4B9B70FA53C73FB694}"

3. The 2nd reference is prepared but not active "{ REF:N@I:ABD4"...
4. Delete the blank past the second "{" - making the second refrence become active.
5. Update entry
6. Waiting circle icon appears - exception windows shows up (after some ten seconds).
