Wolfram Cloud does not evaluate cells using Shift+Enter

Question

When one clicks Shift+Enter on or evaluates a cell, it prevents you from typing/editing it, so it was thought

How can I prevent SHIFT-ENTER moving the editing cursor?

would stop this, but it did not. Then, a link in a comment below its answer was tested from

Make cursor stay in input cell.

The referenced code evaluated was

 With[
  { nb := EvaluationNotebook[]
  , c := EvaluationCell[]
  }
, With[
    { cv := CurrentValue[nb, {"TaggingRules", "LastCursorPosition"}]
    , pos := FrontEndExecute@FrontEnd`UndocumentedGetSelectionPacket[nb]
    }
  , With[
      { savePosition := (
          cv = If[MemberQ[pos, "CharacterRange" -> _], Last["CharacterRange" /. pos], False]
        )
      }
    , SetOptions[nb
      , CellEventActions :> {
          {"MenuCommand", "HandleShiftReturn"} :> savePosition
        , {"MenuCommand", "EvaluateCells"} :> savePosition
        , PassEventsDown -> True
        }
      , CellEpilog :>  If[
          IntegerQ[cv]
        , SelectionMove[c, Before, CellContents]
        ; SelectionMove[nb, Next, Character, cv]
        ; cv = False
        ]
      ]
    ]
  ]
]

However, it made it so that when clicking Shift+Enter to evaluate a cell, nothing happens. This issue only is on the notebook where this code was evaluated.

Unfortunately, refreshing the page, closing/reopening the tab, clicking “Reset to Default” in “Preferences” for “Evaluation”, and clicking “Evaluation” then “Restart Session” and “Quit Kernel” did not fix this issue. These steps usually reset presets for Wolfram Cloud, but not do so for this specific one.

The version is 14.0.0 for Linux x86 (64-bit) (December 13, 2023).

How does one make Wolfram Cloud be able to use Shift+Enter and fix this glitch?
