Is it normal for Roblox to have this certain glich?

I was ingame roblox and when testing, my game just freezed and then gliched out of nowhere is it a roblox game glich or script glich or computer glich

it may be your computer or it may be roblox, or it could be a script in the game that contains loop without a wait.

Well if there's a While true do scripts there always add wait() so the game won't freeze

While true do
print("Code here")


wait()

end
