Changing resource pack that overrides a font crashes JVM

Changing resource pack that overrides a font crashes JVM. Not Minecraft crash.

I'm making a font resource pack for upcoming 1.20 version, so I tried to reload it to apply changes. And then BOOM! The JVM has crashed.

This occurs when triggering some event for a resource pack, such as changing the order, disabling, pressing F3+T to reload, ᅟor quitting Minecraft.

The font resource pack overrides 'default' font using a truetype font (.ttf) file.
