I have filed an issue:
https://github.com/deltachat/deltachat-core-rust/issues/1350
Could you also send the log from .config/DeltaChat/logs folder?
Also if you know how to compile deltachat-desktop from source, it would
be very useful if you recompile rust-core with debug information and
produce a crash report with a backtrace that contains function names.
How do you install your deltachat-desktop?
