Sorry about this trouble. Looking at the crash report, it does look like a GPU error. I am hopeful that your issue is resolved by now. If not, would recommend checking by turning off GPU performance (CTRL/CMD + K > Preferemces > Performance > Uncheck GPU performance).
Also, we've recently released an update for Illustrator 2021 (v 25.2.3) which contains some stability fixes. If you are not already on v25.2.3, then we recommend you to update to latest version.
