Crashing while editing text

[arielaB833]

Hi there.
My 2021 after effects keep crashing over and over while i'm trying to edit my text layer. It's happens when i'm trying to change the color of part of the paragraph and it happens when i'm trying to do simple edit options. i don't know what to do.

Without any info about your system, font usage, other contents of the composition and possibly things like your language settings nobody can tell you much. The error is at the composition renderer level and might in fact not have anything at all with the font but may be caused by something else.

So, I'm working on mac Big Sur 11.3.1. after version - 18.2.0.

I't happens with all the fonts I have checked (Arial, helvetica, hebrew fonts). My type setting is on south asian and middle... I chane to latin - It happens also. 

composition setting- full HD 25 fps...
It happens also when i open a new project - on an empty comp.
