Safari blanked windows on monterey

[EsTriFee]

So installed monterey just two days ago and everything worked fine and all up until today when i accidentally pressed cmd + q instead of cmd + w to close a tab on Safari. No worries happened before just fire up safari again and it will bring everything back like it was, or so i thought it seems. Get home hours later and try to look at other windows i had open of safari and they're all just blank, all the tabs i had opened just gone and reduced to one starter page. This happened to all other windows except the one i was using at the time. (i used new windows for tabs like you would tab groups in the new version i guess). Has anyone had this happen? Tried to google the issue but nothing similar seemed to come up. Is there a way to get back all the other windows with other tabs? (Already tried open windows from last session to no avail. it just doubles the amount of blank windows open all making my mac slow to a crawl and safari unresponsive unless i wait like 10 mins for it to load up)

I’m having the same issue on a M1 max.

Opening safari does nothing or shows an empty window without controls or any content, literally just an empty window frame.

I’ve tried clearing cache, deleting all extensions and even reinstalling after exhausting any solutions found via Google. Hoping someone has a solution to this!

Here's a quick follow up in case anyone else encounters this problem. Despite uninstalling the adguard extension, there were still associated files installed -- I can't say for sure if they were causing the issue although deleted them anyway. If anyone resolves this issue in the future with a more elegant approach, I'd love to hear about it.

Solution:

1. Quit Safari if running
2. Open terminal (ensure it has "Full Disk Access" in System Preferences/Security)
3. mkdir ~/safari_backup
4. sudo rm -rf ~/Library/Containers/com.apple.Safari.* ~/Library/Containers/com.adguard* ~/Library/Containers/com.betafish.adblock-mac*

This worked for me, Safari is now back up and running. Please only do the above if you know what you are doing and do not care about data loss on your Mac, a mistyped rm -rf command will ruin your day.

I'm on a 2017 15inch macbook pro, and unforuntaly that wasn't the issue for me, safari would load eventually its just taht it seems to have forgotten all the other tabs i had open in other windows and decided to reset them to just a starting page window. But glad that you managed to fix your issue
