Problems After 14.2 Download

Many problems with 14.1 have not been corrected with 14.2 update. Safari still crashing frequently and freezes up the entire computer. Takes sometimes up to one minute and cannot open anything right away to “quit” Finally releases so I can quit still frozen Safari page and when reopen Safari freezes immediately. Only way to resolve is turning off the computer, restart. But freezes again soon. Also Keyboard keys don’t respond well intermittently, sluggish and I keep typing and the text catches up. Then it has been running hot with 14.1but seems to have improved with 14.2 What will fix these issues please.
