I just updated Edge on a Win 10 laptop to 122.0.2365.63. Edge will no long display any web pages, including edge’s own pages like settings & help etc. The message is “This page is having a problem. Try coming back to it later. You could open a new tab or Refresh this page. Error code: Out of memory”. Refreshing produces the same page. Opening a new tab produces “Not enough memory to open this page”…
UPDATE!! Nails89 on this thread relates this issue to “enhanced web protection” being enabled in privacy settings. I have this enabled, as well as strict instead of balanced. I can’t load the settings page & don’t really want erase my settings & data by altering my Edge user folder in AppData as per the linked suggestion, so instead I downloaded a batch file from option 4 here (since I can’t load settings): Enable or Disable Enhanced Security Mode in Microsoft Edge Tutorial | Windows 11 Forum
This worked! Edge will open & work as normally. However as stated on the tin, it greys out some of the security options in settings, so you cannot alter them…
Suggest quickly toggling that security setting off, & switching the setting underneath it from strict to balanced, before the browser updates itself. Obviously that setting will need to remain off until MS provides a fix.
