Windows 11

This has been going on since 1 or 2 Opera updates ago, but I don't know if that's what caused this. I did report it when it started happening.
When I open a new tab, type a website name, and then hit ctrl + enter to autofill the www. and .com, the search does not initiate. If I re-select the URL bar and hit enter again, it will initiate, and if I manually enter the .com it works fine. This isn't happening in Chrome, so I know it's an Opera issue.
I made a fresh profile, which did fix it for about a day and then it stopped working again today. I have no extensions beyond what's built in (ad blocker), and disabling that didn't help. Disabling mods didn't help, clearing history/cache/cookies didn't help, and everything has been reset to default otherwise.
