DVA Core Error. Premiere will not even open. Please Help!

Please J, are you running US English, no other language, keyboard, etc. Win 10 or 11?

Where did you find the setting?

I'm having the exact same issue today.

I went to Windows security but couldn't find a solution.

I just found the setting, it's certainly worth a try. Mine was off. I turned it on, and got into PP no problem. It may have seemed slower, but I can't say for sure on that.

I'm on windows 11, got the same error. The way i got it to work was by allowing the blocked (premiere pro) apps in: Windows Security -> Manage Ransomware Protection -> Allow an app through Controlled folder access -> Add an allowed app. I don't know this even exists in Win10 but i hope this helped a little...

Localizer is typically a language element. I'm stumped if Adobe Cleaner does not work. I'll suggest you try contacting Adobe, here's a link: https://www.adobe.com/about-adobe/contact.html. Let us know what you find out.

Keyboard is in english. Running Windows 10

Do you have a non english keyboard, or are running in non-english? Windows I'm guessing

UPDATE: I work for a school and this is technically their computer. Even though I've had this computer for almost a year now and I've never had this problem before, for some reason this error now happens when I am at home, not when I am at school. Thankfully I am able to use Premiere at work. Any idea why this message comes up when I am at home? I tried using the Adobe cleaner utility, but no luck. (See previous comment). 

Looks like that didn't work. 😞

I ran the cleaner to it's max, running it on all adobe files and such. Had to reinstall creative cloud and Premiere, but the exact same message is still coming up.

It looks like you should reinstall. If it comes up with the same errors, you can run the Adobe Cleaner after you uninstall the programs and before you re-install them: Also, reboot your computer between steps even if you are not asked to...

Be sure to backup your preferences, workspaces, etc before you run the cleaner.
