What happened was that sometime last week I received an upgrade to one of the three, can’t remember exactly but believe electron, after which Signal and Riot didn’t work any longer with the error above.
At that time I didn’t bother and was hoping that another update will fix it, which it did. Monday or Tuesday I received an update of Electron and things were back to normal. And yesterday another one came in which broke things again which made me look into things.
Yay gave me the versions I am showing above yesterday which didn’t fix the issue. This morning I eventually found the hint to try the link and I am back in business.
By the way, I don’t think I am dealing wit updates not applied properly because I do reboot at least once a day because I am moving this machine from dock to undocked which doesn’t go well with intel-virtual-output unless I reboot.
