Brave crashes on opening settings

Brave crashes immediately when you click on settings through any method (eg, burger at top right, or ‘manage extensions’ or brave://settings).

I’m on a Mac using OS Big Sur.

I tried an old workaround listed here. But this now causes Brave to crash.

I need to be abke toi manage my extensions. Anyone know any workarounds?

Thanks!

Other things that cause Brave to crash include:
‘About Brave’
Clicking the Brave Firewall + VPN butting, top right.
Clicking the wallet icon, top right
Choosing Window > Extensions

I switched to a different tab group, Brave crashed again, and now crashes every time I open it. It’s now totally unusable.
