Sprint mechanic not working when player presses another key which is a keybind for a UI

[fierce mica]

local RNS = game:GetService("RunService")


local StaminaDrain = 0.1
local RechargeTime = 1

local char = script.Parent
local hum = char:WaitForChild("Humanoid")

local lastSprint = math.huge

local isSprinting = false

local function sprint(actionName, inputState, inputType)
    print("Sprinting")
    if inputState == Enum.UserInputState.Begin then
        isSprinting = true
    elseif inputState == Enum.UserInputState.End then
        isSprinting = false
    end

    if isSprinting then
        hum.WalkSpeed = hum:GetAttribute("SprintSpeed")
    else
        hum.WalkSpeed = hum:GetAttribute("BaseWalkSpeed")
    end
end


CAS:BindAction("Sprint", sprint, true, Enum.KeyCode.LeftShift)

RNS.RenderStepped:Connect(function(delta)
    local Stamina = hum:GetAttribute("Stamina")
    if Stamina < StaminaDrain then
        isSprinting = false
        hum.WalkSpeed = hum:GetAttribute("BaseWalkSpeed")
    end

    if isSprinting and Stamina > 0 then
        hum:SetAttribute("Stamina", Stamina - StaminaDrain)
        lastSprint = tick()
    else
        if tick() - lastSprint >= RechargeTime and Stamina < hum:GetAttribute("MaxStamina") then
            hum:SetAttribute("Stamina", Stamina + .3)
        end
    end
end)```

Whenever a player then clicks for example "F" which opens up a GUI in the game, the player can no longer sprint and the sprint function does not fire

When the player begins sprinting it prints "Sprinting" once and then again when the player stops sprinting

This is the scrpt to open the UI

which breaks it, I think

    if typing then return end
    if input.KeyCode == Enum.KeyCode.F then
        UIclick:Play()
        if debounce == 0 then 
            debounce = 1 
            CloneChar()
            for i = 1,10 do 
                wait(0.02)
                MenuFrame.Position = MenuFrame.Position + UDim2.new(0.012,0, 0,0) 
            end
            debounce = 2 
            
        elseif debounce == 2 then 
            debounce = 1 
            DestroyChar()
            ChoiceFrames.Visible = false
            for i = 1,10 do
                wait(0.02)
                MenuFrame.Position = MenuFrame.Position - UDim2.new(0.012,0, 0,0)
                debounce = 0 
            end
        end
    end
end)```

Thanks
