Crash with the custom fonts

trying to put a /title or a /tellraw with custom font crashes I`ll leave a resorce for you to check

these are the command(in spanish)

/title @s title [{"text":"Texto con "}, {"text":"fuente personalizada","font":"minecraft:pacifico"}]

/tellraw @s [{"text":"Texto con "}, {"text":"fuente personalizada","font":"minecraft:pacifico"}]
