I have a password protected pdf. I can open it with the correct password. Then I tried to remove the protection going through below steps.

1. Tools
2. Protect
3. Advance options
4. Security properties
5. Changed security method to "No security"

At the fifth step, I got a prompt to enter the password again. I entered the same password I used to open the document, but it says the password is incorrect.

I checked for non-functioning keys of my keyboard and Caps Lock key. I am sure I entered the correct password.

I am using Adobe Acrobat (64-bit) 22.003.20282
Today(13th Dec 2022) I upgraded to Adobe Acrobat pro.

My password is something like this(not the exact one) : 26May1996235683
