Hi @Claire Heng
Hope you are doing well and sorry to hear that
Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. If the file is stored on a shared network/drive please download it to your computer locally and then try again.
What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 22.3.20281 (Mac) or 22.3.20282 (Win) installed. Go to Help > Check for updates and reboot the computer once.
Also, check for any missing/pending updated for video driver and firmware on your system and try updating it and check.
Also try to repair the installation from the help menu (Win Only) and see if that works.
Please try to reset the Acrobat preferences as described here https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-defau...
You may also try to create a new test user profile with full admin rights in Win or enable the root account in MAC and try using the application there and check.
