#First copy all online players to a temporary scoreboard
execute as @a run scoreboard players operation @s <tempScoreboardName> = @s <ScoreboardName>

#Delete the original scoreboard
scoreboard objectives remove <ScoreboardName>

#Create the scoreboard again
scoreboard objectives add <ScoreboardName> <trigger>

#Copy all players from temporary scoreboard back
execute as @a run scoreboard players operation @s <ScoreboardName> = @s <tempScoreboardName>
