I’ve always had fine experiences with 1Password both on iPhone and my Mac. With how bad Windows 11 is and continues to be, I wonder if your ire is misdirected. On my work computer (Windows) I’ve had a plethora of stability issues across a variety of programs/applications including ones developed by Microsoft.
Maybe, but I've found Win11 to be stable in general. Not to say there aren't issues elsewhere.

Seems like it's been a recurring issue for years, even on Win10.
