Chromium won't load

chromium stopped loading last night.
don’t know what happened.
fresh boot, and it still won’t load.
click on it, it shows a few chromium things starting in system monitor, then stops.
i’ve uninstalled and re-installed through the software part.
finally installed firefox to get here to ask.
would like to get it working again.

it was working, then after i closed it i tried to re-open it, and as i stated above.

Probably there is a corrupt profile - this would be stored with the snap - simply removing and reinstalling a snap such as chromium will not clear out the profile since snap data is remembered unless you forcefully remove it.

I’m not familiar enough with chromium to help you create a new profile from the command line

Try running chromium-browser --help or whatever the chromium command is and see what is there.

e.g. in Firefox you would do something like firefox -P to create a new profile (my memory may not have got the exact command line switch correct!)

Alternatively you can forcefully purge chromium before reinstalling i.e.

snap remove --purge chromium-browser 

… or again whatever the snap name is for chromium

Hope the above helps in investigating further.

it was really strange.
it was working, then after closing, refused to open again.
i’m not a command line person familiar with linux.
although exact instruction i take well.
so the line snap remove - - purge(etc) would be a direct one as it is written?
guess i should have made that clear.

Maybe an easier way for testing a new profile for Chromium :

just rename the folder
You may do that from your file explorer, or using command :
mv ~/snap/chromium ~/snap/chromium_bad

Then relaunch chromium. It should start like it was its first time and create a new folder ~/snap/chromium

If no improvement, try relaunch Chromium browser from the terminal, using
snap run chromium
and look for error messages in terminal. The command for launching depends on how you’ve had installed Chromium ( ie. did you use apt install or snap install or software application ).
