Send by email option is not working Since September 2021, a Microsoft problem...?

Hi All,

Since Adobe Acrobat Reader DC 2020 - Update - 21.007.20091 and Adobe Acrobat Reader DC 2020 - Update - 21.007.20099, Attach to email (or send by email) option is not working and this happens on dozens of pc, tried https://helpx.adobe.com/acrobat/kb/attach-to-email-not-working.html#sa_src=web-messaging but it didn't help either. .

I've tried to isolate some events and that what comes out ( translated from french):

Eventid 505 Microsoft-Windows-Application-Experience / Program-Telemetry Information Compatibility fix applied to C: \ PROGRA ~ 2 \ MICROS ~ 3 \ Office14 \ OUTLOOK.EXE.
Eventid 505 - Microsoft-Windows-Application-Experience / Program-Telemetry Information Compatibility fix applied to C: \ Program Files (x86) \ Adobe \ Acrobat Reader DC \ Reader \ AcroRd32.exe.
Hotfix information: Adobe Reader, {91b7d18d-6dda-42ac-a6e4-ef1b22e49a23}, 0x80010101.

RuleName : Adobe Acrobat Reader DC Protected Mode
Application that made the modification: C: \ WINDOWS \ System32 \ svchost.exe

Eventid 2006 - Microsoft-Windows-Windows Firewall With Advanced Security / Firewall Information A rule has been removed from the Windows Defender Firewall exception list.

RuleName : Adobe Acrobat Reader DC Protected Mode
Application that made the modification: C: \ WINDOWS \ System32 \ svchost.exe

Eventid 2004 - Microsoft-Windows-Windows Firewall With Advanced Security / Firewall Information A rule has been added from the Windows Defender Firewall exception list.

IMHO 100% all pb are coming from there, but i hope someone can light my findings plz :

1/who in the community, was aware that microsoft was modifying adobe pgm through telemetry and without our knowledge or consent ?
2/Can I turn this behavior off and are there any consequences on M $ or Adobe pgm ?
3/Who knew that SVCHOST changes Acrobat Reader Firewall rules in the same second (Eventid 2004 and 2006) ?
I spent the last 2 months Hating Adobe but I believe that it is not their fault ... my apologizes.
Thank you for your clarifications.
