Thank you for reporting. I can confirm the crash (with version 21.04.3). 

Lock all needed video and audio tracks the clip needs. Insert the clip into the timeline. Nothing happen. Unlock the video track and insert the clip again -> Kdenlive crash. I could not create a gdb log as Kdenlive is frozen.
