Application Freezes related to acrobat.exe and oleacc.dll

Hi Adobe Community

We are reporting a lot of application freezes in our company. 
The users, who are affected excpecting freezes 20 times a day, each lasting from 30 seconds to a minute. 

Sometimes it's Outlook, sometimes it's Acrobat Reader himself, sometimes it's the phone software or any other software.. It doesn't matter which software is freezing. 

Everytime we report a freeze of a software, in the Event-Viewer, under Application we have at the time of the freeze the following entry:

Event ID 1000 - Application Error
   

    The description for Event ID 1000 from source Application Error cannot be found. Either the component that raises this event is not installed on your
    local computer or the installation is corrupted. You can install or repair the component on the local computer.

    If the event originated on another computer, the display information had to be saved with the event.

    The following information was included with the event: 

    Acrobat.exe
    22.3.20263.0
    634c3bf9
    Oleacc.dll
    7.2.19041.746
    24cdd509
    c0000005
    000000000000628c
    3064
    01d99396f61ec861
    C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe
    C:\WINDOWS\system32\Oleacc.dll
    8048e687-5ff0-47e0-8ff6-bf47e2a57a3d

    The handle is invalid

Additional Info:

OS: Windows 10, 21H2, Build 19044.3086

Adobe Reader: 22.3.20263.0

oleacc.dll: 7.2.19041.746

What have we tested and found so far:

• We tested Microsoft Edge as PDF Viewer. The users who had problems before, could work all day long without freezes with Microsoft Edge.
• Freezes (also in other software) only happen when adobe acrobat is running. 
• We updated Adobe Acrobat Reader to the laest version, but without success. (Also with uninstall before..)
• Reregistering the oleacc.dll also does not bring the solution

Does anyone have any idea what could be the problem here or what else we can try?

Thanks in advance and Regards, 

Dominic
