File/computer scanner doesn´t work

Hi everyone.
Since I installed AVG on my mac I have not been able to scan individual files or the whole computer once. The message I am getting is "Unable to initialize AVG virus scanner controller! (Requested operation failed.)"
Already tried uninstalling directly from the AVG uninstallervand reinstalling so that solution is discarded.
I´m on a mac running macOS Big Sur.
Thank you all.

Hello Juan,

We are really sorry to know this.
We will check and help you with this issue.
May I know the version of your AVG Internet Security program being installed on your Mac OS please?
You can refer to this article: | AVG (https://support.avg.com/SupportArticleView?l=en&urlName=Mac-AVG-Antivirus-malware-scan&supportType=home) on how to scan your Mac with AVG program.
Thank you and keep us updated.
