Big Sur Problem?: "You do not have permission to open the application"

With the new update off MacOS I have encountered an issue with opening quite a few off my applications as it says within the title I do not have the permission to open the application. Has anyone had any similar problems to this if so what have you done to resolve this and why does this occur.

Yes, I have the same situation with some of my apps too after updating to Big Sur.
Tried to disable Gatekeeper in terminal:
sudo spctl --master-disable

But it doesn't help.
xattr -rd com.apple.quarantine <app>

then execute it and it'll ask for admin permissions ;)
Same issue, some of my Apps do not open I get this dialog window saying "You. don't have permission to open the App, contact Your computer or network Administrator for assistance" Also it happens when I want to install an App. I changed permissions and it did not work. Any help is appreciated. Thanks in advance.

xattr didn't help, any idea why?

Also tried read/write admin permission, Gatekeeper and also SIP

Same problem here. Things I've already done:

Disabled gatekeeper
Disablde System Integrity Protection (SIP)
Blocked ocsp.apple.com in /etc/hosts
Verified Sharing and Permissions to Read&Write via file info (cmd-i)
Added check to the App in Full Disk Access in Security & Privacy

Still no luck.
Same! Nothing seems to work!!
I reapplied the permission on the folder that I was scanning to. Works on Canon copiers.

Still having issues with HP smb scanning
I also have the same issue. I also have tried every thing listed here and more.

One cause of this on Apple silicon machines, including the DTK, is building your app for arm64e rather than arm64. See this post for more.
