Question "Access Denied" error for a folder on my External HDD ?

[EHABSA]

I know this question has been asked before, but I tried multiple solutions and none worked. I am trying to access a folder on my external hard drive but it says "Access Denied". The folder's name is "Local Disk". I made this folder on my old school laptop about three years ago. Later, I moved it to an external hard drive, and it's been working fine since then until suddenly it displayed that error, even though I made no changes to my laptop, administrator settings, or anything else.

My OS is Windows 10.

Take ownership of the folder. Execute from elevated command prompt.

takeown /f E:\foldername /r​

icacls E:\foldername /reset /t​

( E: - assumed drive letter for your external drive. Change to appropriate drive letter)
Do not run those commands on C:\windows or you'll have to reinstall.

This will not fix anything, if you have encrypted data on your external drive.
Then you can access it only from pc, where you encrypted it.
