"Incorrect client instance"

Hello.
My game has been working fine until yesterday.
I randomly started to get this error and still can't fix it: https://prnt.sc/jq95nt
My OS is Windows 10.
I use Avast antivirus.
I put exclusions for both the game launcher and both versions of the game executables on the firewall, and the entire folder I have my GamezBD files in is excluded on both. Avast and Windows Defender.
I restarted (Both the launcher and my PC) multiple times after adding the exclusions.
I tried launching as admin.
I even tried disabling Avast, Windows Defender and the firewall but it still didn't work.
Any and all suggestions would be welcome and appreciated.

 

a force check, or a loader fresh installation would help.

 

I've already done those.

I uninstalled my AV, deleted all files related to BDO, and redownloaded GamezBD via torrent and redownloaded the launcher too, but I am still getting the same error.

UPDATE
I had to reset my OS to fix the issue.
I wish there was another way. I don't want to reset my OS whenever I get an error.
