AdobeAcrobatDC problem on WINE 6.0

[Payam]

AdobeAcrobatDC version 20.013.20074.18474 was working flawlessly on previous version 5.0 but stops working correctly on stable version 6.0 (with same symptom for Development and Staging branches) on Ubuntu 18.04 Linux 5.4.0-65-generic #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
the program starts normally and even displays file previews correctly, but by opening any PDF document it stops responding.

My temporary solution is downgrading to version 5.0.3:

sudo apt install --install-recommends winehq-stable=5.0.3~bionic wine-stable=5.0.3~bionic wine-stable-amd64=5.0.3~bionic wine-stable-i386:i386=5.0.3~bionic

for me latest acrobat dc works correctly- see viewtopic.php?f=8&t=34799#p131318
from your log I see that you have not installed native riched20 windows dll - please install it

That resolved my problem, however I didn't understand why version 5 didn't need these native dlls, and how these 3 commands find and install native dlls, but your solution works perfectly.
Just with these 3 commands:

winetricks mspatcha
winetricks riched20
winetricks vcrun2015

Thank you,
