My desktop computer is an iMac running Big Sur,
There is 32Gb RAM and plenty of disk space.
It's been working perfectly until 5 hours ago when the following faults occurred:
Thunderbird started displaying multiple copies of each message;
Chrome failed to load.

I uninstalled Chrome and Thunderbird, then re-installed the latest versions..
Now I can't see any of my email accounts and Chrome still won't load.
I need someone to sort this out ASAP.
I have AnyDesk and TeamViewer.
