Application: kate (23.04.3)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.4.6-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.6 [KCrashBackend]

-- Information about the crash:
I was trying out the LSP Plugin with a Rust project, which I opened with "Open Folder". I had 5 files open and experimentally saved a session. I then closed the "project" using the red cross button in the toolbar, then tried to open the saved "session" from the menu bar. The kate window appeared to close, re-open, then crash in quick succession.

I don't really know what I was doing with project/sessions because I'm still learning how they work. Hopefully the stack trace is useful!

The crash does not seem to be reproducible.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
