There may perhaps be a fix, IF you can get to the Settings panel.
Google caused quite an upset last year when they announced the introduction of the FLoC trials. (FLoC = "Federated Learning of Cohorts"). This is all part of Google's big push toward greater internet privacy, and the elimination of 3rd-party cookies.
Basically, instead of ads being individually targeted at users, FLoC notices when a group of people all have the same interests, and sends suitable adverts to that group as a whole. Google received a lot of flak over this, and have since replaced it with "Privacy Sandbox" trials instead. The annoying thing about this is that it's enabled by default, and you have to deliberately opt out (as opposed to opting-in).
I disabled this in Chrome months ago. When Slimjet 33 appeared the other week, it also seemed very unstable. I've just now disabled Privacy Sandbox trials here, too; touch wood, it seems more settled. It's early days yet, though.
---------------------------------------------
To disable it, go into Settings->Privacy & Security. 'Privacy Trials' is down the bottom. If it's on - which it probably IS - follow the link, and disable it. Then shut-down, and re-start the browser.
As I say, this MAY be barking up the wrong tree, but.....it's worth a try. Apparently, early instances of this caused widespread crashing of Chrome in the middle of last year when it was first introduced, so it's possible there's still bugs in the system; Slimjet, in particular, is always built around versions of Chromium that are a few releases behind.
(@all :- Guys, is this ONLY occurring for you in Bionicpup64, or is anybody having issues in other Puppies, too?)
Mike. 
We can't rule anything out, yet....
