Crashing when resizing text

Hi default9fxlk51044ri,

Sorry for your issue. 

What are your system specifications (CPU, GPU, RAM, OS version)? Also, what's the exact version of After Effects you're using: https://community.adobe.com/t5/after-effects-discussions/faq-how-to-find-the-exact-version-of-after-effects-you-re-using/td-p/9972137

Let us know, we're here to help.

Thanks,

Nishu

Start by setting your composition to software-only rendering. Other than that try the same procedure with a different font. Could just be a "bad" font causing mayhem. anything beyond that will require more info about what Mac and version of OSX you are actually using, comp settings, screenshots of the actual project and so on.

Hola, espero pued a ser de ayuda con este comentario: 
Tratat de resetear tu ventana de texto y de crear un nuevo proyecto en una ruta diferente. Tuve un problema similar hace algunos meses y al parecer era por una falla en mi unidad de disco duro.
Se soluciono cabiando la ruta y ya posteriormente tuve que cambiar de SSD.

Saludos
