Dear Maintainer, I'm also having this problem, after upgrading via apt get. chromium becomes impossible to use. I even have to downgrade from 83.0.4103.116-1~deb10u1 to 80.0.3987.162-1~deb10u1 for get an usable version of chromium.
In the 83 version I have several crashes after some time using the browser and it just crashes with no messages, and facing a really slow browsing experience.
