Hello @Tarek Elsayed,
We understand that encountering technical issues can be frustrating. Would you mind trying to run Illustrator under Safe Mode (Windows / macOS) and checking if it helps? Also, try running Illustrator under a different administrator account (Windows / macOS) and share your observations.
Looking forward to hearing from you.
Thanks,
Anubhav
Hi, sorry for the late reply.
I was away for a few days and when I came back, I found ou everything is working normally 🙂
I'm not sure what happened but I'm glad that it works fine again.
Thanks you all for your time.
