PS beta crash on MacOS 11.6 - PS no longer compatible with Big Sur?

Hi,

Latest PS Beta crash at startup on MacOS 11.6 with the crash report saying: 

Symbol not found: __ZNKSt3__115basic_stringbufIcNS_11char_traitsIcEENS_9allocatorIcEEE3strEv
Referenced from: /Applications/Adobe Photoshop (Beta)/Adobe Photoshop (Beta).app/Contents/MacOS/../Frameworks/AdbePM.framework/Versions/A/AdbePM (which was built for Mac OS X 12.0)
Expected in: /usr/lib/libc++.1.dylib

I guess the part "which was built for MacOS 12.0 explain the issue.

Is this a bug or is PS no longer compatible with mMacOS 11.x? Why does the CC installer didn't tell that this version is "not compatible" as it does for Lightroom?

I have a 2014 iMac and cannot upgrade to MaxOS 12.

Thanks
