"Forbidden Invalid authenticity token" on website login attempts

Version 1.22.71 Chromium: 89.0.4389.114 (Official Build) (64-bit)

I have been getting the message above after attempting to login to some sites including:

However, Opening a Private Window resolve this issue. Google Chrome on same computer work fine. Any way to resolve?
