Hello @Tanha32024900jnc2,
Sorry to hear about this experience. Would you mind trying to install the Arabic version of Illustrator (https://adobe.ly/3Qv53sA) and checking if it helps?
If the problem persists, kindly share more details, like the exact version of the OS/Illustrator and the exact font name/foundry, so we can investigate this further.
Looking forward to hearing from you.
Thanks,
Anubhav
