I tried using the file associations as suggested in the link in the previous comment and instead of two crash dumps I got one.

Hello @amitavmohanty01, you've described the issue being tracked at #6811. Steam is processing shaders seen during the game session in the post-game-run. If you were to wait a while, Steam should close after finishing this work. Also, disabling shader pre-caching should avoid this issue.
Closing as a duplicate.
Get rid of cjobmgr. Its polling a nonexistent process.
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
In KDE Plasma, Steam was having shut down problems. The steps are described below. After step #5, steam is supposed to quit gracefully but it became a defunct process.
To dig deeper, I ran it from command line. I got the following log.
I am also attaching the crash dumps herewith.
