Steps to reproduce the issue

1. Download qgis-test.zip
2. Open project
3. Edit "test" layer
4. Try to split line as in screenshot above
5. QGIS crashes

@kapiwko could you please clarify what tool are you using? Is it the "Split Features" tool?

[kapiwko]

Is it the "Split Features" tool?

yes

[uclaros]

Probably related to #50948 and the changes in #47306

[agiudiceandrea]

I can confirm the occurrence of the crash with QGIS 3.28.2 also on Windows. It seems to me the crash doesn't occur using QGIS 3.22.14.

The crash also occurs using the latest available 3.29.0-Master (33467dd) from OSGeo4W

^^ That's a different stacktrace you got there!

^^ That's a different stacktrace you got there!

@uclaros Yes, but using the same Split Features tool...
