Tested with a bow like mentioned and it works 100% as intended, even without slowdown and whilst jumping and moving. Maybe a short video recording would help explain what you are meaning.
Like Ehylo said, the error is not strictly limited to auto-updating to the latest build.
You will recieve this error if you use 1.16.5 Forge regardless of what you do. You may also recieve it on unofficial launchers or custom modloaders.
