I am aware that im running a super old version. The Pop!_ OS repos don't want to update for some reason 
SUMMARY
After selecting a category (on sidebar) in discover, it crashes. However, it only does if i am not in a search 

STEPS TO REPRODUCE
1. Open discover
2. Open category in sidebar

OBSERVED RESULT
It hangs for a few seconds and then crashes.
(when using gdb, the window never closes and it just hangs until i manually kill it)
output from gdb after crash: 
```
(process:13609): GLib-ERROR **: 23:09:44.724: Creating pipes for GWakeup: Too many open files

It should enter the category and display without die

SOFTWARE/OS VERSIONS

\/ (idk if this helps) \/
I have gotten a completely unrelated error that also complains about "Too many open files". For that one i fixed it by running `echo 256 | sudo tee /proc/sys/fs/inotify/max_user_instances`. I tried doing this and running it again but it still crashes.
