@xinyangcarlu.li as another user, Ctrl + LMB click is a surefire way to enter a value into a field. i’ve ran into this issue as well on and off and even though one extra click is not as convenient, it’s a ways to ensure it consistently allows me to enter new values.
unless this is a new bug that prevents you from clicking into the field altogether, then it’d certainly be something to elevate up to the devs.
You can try setting runLoops.main.manualModeEnabled = false
in the apps/isaacsim.exp.full.kit Kit experience file as a temporary workaround.
This setting ensures that UI field interactions (like double-click edits) run in the normal update loop rather than manual mode, which can restore expected behavior in some cases. Please let us know if this resolves the issue on your end.
