Q: And if you press "C-h l" (that's the letter ell, not the digit one) after pressing the mouse on the tool bar, what does Emacs show in the *Help* buffer it pops up?
A: The same text without changes: C-h 1 ;; view-lossage

Q: So it sounds like Emacs doesn't get some of the mouse clicks in your case?
A: Yes
Q: What about dragging the scroll bar's thumb with the mouse-does that work?
A: Works as expected
Q: Maybe review the mouse settings to make sure nothing there prevents these clicks from being reported to Emacs?
A: I do not know what mouse setting to review. And in Emacs 29.3 everything works fine. And in What’s new I did not find essential changes in mouse operation
