Chromium browsers won't open

MXC48

I use vivaldi daily as a browser and until yesterday everything worked perfectly, then suddenly without me touching anything it refused to open... I've tried removing and reinstalling it, I've tried the flatpak version and eopkg but nothing works even if I delete the vivaldi files in .conf
So I've tried other browsers and librewolf as well as the firefox variants work, but all the chromium-based browsers (brave, chromium etc) don't work and when you click to open them the cursor tells you that the process is loading and then nothing.
being a new user I haven't found the logs yet but if you tell me where to find them I can try to provide them.

Try launch VIvaldi via the terminal and see if any useful outputs shows up.

all I had to do was make a post about a problem that's been bothering me for a while, and it solved itself the way it happened...
So much the better 😆

If it happens again, check the terminal out put and gnome log app and post it on the forum.

Today i was trying to use Brave browser and noticed, that it does not start. When started from console I get those errors:

I have tried to google for these errors, but this did not helped, as all suggested solutions for me looks irrelevant.
I have tried to remove and install brave-browser, but this did not helped - I get same error.
It looks like some kind of Gtk library errors, but I don't imagine how to fix them...

In your .config directory, you’ll find a folder named BraveSoftware. Try renaming it to something else, like BraveSoftware.bak. This might help you start fresh.
