CEP Extension crashes on new Illustrator/Photoshop 2021 release

Found two issues on Illustrator 25 and Photoshop 22 (CEP 10) on macOS with a secondary monitor connected. I have attached a simple CEP extension for Adobe to investigate the issues. Download the zip file from

https://github.com/zhangusc/github-demo/files/5432064/com.esri.cep10crash.zip. Unzip the file and place the folder under your CEP extensions folder on macOS.

Reproducible steps are included in the extension itself (See image below). Both are critical issues affecting all CEP extensions including Adobe’s own “Library” extension across multiple Adobe 2021 apps (e.g. Illustrator, Photoshop, etc.). I hope Adobe can move quickly and have a fix for those issues.
