Just found a possible solution. I have a 2020 MS, and recently the browser started crashing randomly after a few seconds or more, but always crashing. It was absolutely unusable. I reported it to the local SC (where I have an unrelated appointment next week). They said the problem is caused by "a lack of available memory", and they suggested I clear all my navigation history. It took me a while to manually delete each stored location (by swiping right), and when I was done: no change. I did a hard reboot of the car using the Power Off button on the Safety screen: no change. Then I did an MCU reboot with the steering wheel switches: success! For the first time in months, I can view web pages, open links, and do normal web browsing without the browser unceremoniously crashing.
TL/DR: Manually delete all navigation history locations, then reboot the MCU to restore web browser utility. Don't know how long it'll last, but this is a dramatic improvement.
Edit added: I'm running 2022.4.5
