We apologize for the inconvenience caused, as per the description above, the size of all the buttons are significantly larger in Acrobat and the dialogue box open partially off the screen, Is that correct?
Please try to Navigate to Acrobat's Preferences from Edit>Preferences>General>Scale for screen resolution>set it to No Scaling>and click OK.
Check, If this brings any difference.
Also, try changing the settings for Touch Mode to Never from the drop-down options.
You can also refer and try the suggestions from the following Adobe articles How can I reduce the size of toolbar icons? (Accessibility)
Installation of the previous version of Acrobat is not recommended by Adobe his policy affects product and security updates for all derivatives of a product or product version (localized versions, minor upgrades, operating systems, dot and double-dot releases, and connector products).
Let us know how it goes and share your findings.
