I assume you're talking about the order in which apps appear when you first launch rofi. That's in the cache file in ~/.cache as something like rofi3.druncache or rofi-3.druncache (or both). Delete (or rename) them and see if that addresses your issue.
If you truly mean the config file, it's in ~/.config/rofi. Delete or rename to see if it fixes your issue
Looks like some process in your startup scripts (fish profile, etc) have not completed. I have seen this type of thing when NFS mounts are unreachable. Try opening another terminal window... if it does the same thing, press Ctrl+C, then run ps -ef and see what processes are running as you that might be hung
I had a similar problem. I had made a bunch of changes to a document and just closed LibreOffice Calc thinking it would prompt me to save it. It did not. It just exited and discarded my changes. I went in that day and turned on AutoSave.
In 1993, a guy I knew had a Linux server running in his dorm room. I think it was a 0.9x kernel. He dialed into the University network and I was able to telnet in through my own dial up connection to the University. He was running Slackware.
Within a couple months, I downloaded all 30+ 1.44 diskette images and built my own Slackware server. In that time I used Slackware and Red Hat (which then became Fedora before RHEL became a thing). Now I've pretty much settled on Debian for servers and Arch for desktop/laptop systems.
