Hey Dear, I find an issue in it. I got an error " The operation cannot complete because of unknown error [CANT]" and this is the same issue with every version of illustrator. I used illustrator from 2019 and it's worked perfectly before installation of 2021 and after that I got an error of every versions. If I resolved this issue from common file and change its UXP to 00UXP then I got a problem in photoshop and premier as well. Kindly anyone give me a proper solution of this issue. I am waiting your kind response. Kindly resolve this issue as soon as you can. and give me the proper feedback.
