Comment 1 Sebastian 2019-12-20 17:22:12 UTC 
I think i may have something to do with my recent pull, i first pull from git same project that was opened before(i made changes to it on other computer, changes has been committed to repo and then pulled on computer when crash happened). After pull i opened Kdevelop and then crashed occurs. After opening Kdevelop again everything works.

New crash information added by DrKonqi

kdevelop (5.7.211200 (21.12.0)) using Qt 5.15.2

- What I was doing when the application crashed:
Restarting from another crash and probably reloading all the open files before duchain reached 100%.
