Safari will not open any new windows or tabs
Using Safari v15.4 on a 2020 iMac running MacOS 11.6.5.
Safari became unresponsive, and would not open any new tabs or windows. I force quit, restarted the Mac, and tried again. Still the same issue.
If I go under File > New Window or New Private Window, I get nothing. If I choose New Tab, then a small, blank window shows up about ¼ the size of a normal one.
I have cleared the history and cache, disabled any extensions, and restarted again. Same issue.
iMac 27″, macOS 11.6
