Safari is buggy and oftentimes unusable with multiple windows open (macOS 12.0.1)

Background:

I have an M1 powered MacBook Air running macOS 12.0.1. Safari was unresponsive, so I quit Safari and opened it again, and reopened all windows from my previous session (Safari > History > Reopen All Windows From Last Session), as I would do with no issues on macOS Big Sur. However, I noticed some strange things happening after this.

What I have tried so far (without the issues being solved):

• Restarting my MacBook Air
• Force quitting Safari, and opening it again as usual
• Opening a second window without reopening all windows from my previous session

Issues:

• Whenever my cursor hovers and moves over a text field (on Safari only), it flickers from the I-beam pointer and the Arrow pointer until I stop moving the cursor. (Below shows what I-beam and Arrow pointers look like if you are unaware.)
  • When I stop the cursor from moving on a text field, the cursor displays the Arrow pointer, but it is supposed to display the I-beam pointer.
• When I move to a second open window in Safari (with a different Tab Group opened on the second window), additional issues appear.
  • Either the tab bar or the search bar (or both) of certain tabs will appear blank even though a website is open in them.
  • When I click the search bar and type something in it, Safari will not show me any suggestions based on bookmarks, history, etc.
  • Sometimes, when I search something in the search bar nothing will happen, but when I type in a website then it will open a website; I have to type in "google.com" just to search something on Google, when I should be able to just type it in the search bar.
  • Sometimes I cannot open the Sidebar, either.
  • Sometimes Safari just goes unresponsive.

Does anyone know how I might be able to fix this?
