I was able to reproduce this issue on my Go S under SteamOS
Nothing interesting in the controller_ui or controller log, it just seems to read the config a few times:
[2026-02-20 23:25:54] Loading config for appid: 275850

The config is pretty huge though
$ ls -al "/home/deck/.local/share/Steam/steamapps/common/No Man's Sky/GAMEDATA/INPUT/controller_switch_pro.vdf"

The UI freezes for about 15s when you open the game details from the home menu. If you back out of the game the steam client restarts. Changing any settings in the controller UI also causes the UI to restart.
I don't believe InputPlumber is at fault, though the issue may be tied to the virtual deck controller being detected or NMS being confused about neptune controllers. The issue does go away if you change the target device to a virtual xbox elite. InputPlumber doesn't freeze using our standard deck-uhid target and when run in debug mode I don't see any unhandled Steam Input commands being sent to the device that would block.

Using a Lenovo legion go 2 with z1e and 32GB of ram experiencing hard freezes for periods of time when interacting with game details page.
Game I am experiencing this with the most is no man's sky. The freezes really hit hard when trying to change steam input. Freezes will last up to a minute and even then sometimes it won't unfreeze and the client will just crash to the home screen.
Switching inputplumber from the Lenovo legion go 2 to be an emulated Xbox elite controller seems to fix it so thinking it's something to do with how steam Is interpreting the go 2.
