Microsoft Azure Storage Explorer update interrupted, and now will not run at all

Azure Storage Explorer was installed on my machine for several years, and always worked fine.
I updated the software when prompted, and re-authenticated my access credentials many times.
All good.

Recently while an update was installing, I accidentially closed the process, and despite uninstalling and reinstalling (even re-downloading the installation) now Azure Storage explorer will not run anymore on this machine.

Seeing another answer in this forum, I went into Settings.Json file and added this line, but it was no help...
{
  "application.telemetry.userId": "a3abf801-a69f-xyxy-xyxy-xyxyxyaa86xx",
  "application.other.enableAppInsightDiskRetryCache": false
}


The on-screen message is
