workspaces client crashes on launch

When I launch the workplaces client on my usual computer, I see the "preparing your login page" popup, and then it disappears. After that, nothing :-(.

When I launch it from a shell, I see this message:

terminate called after throwing an instance of 'std::bad_alloc'$

and then I have to reset the terminal session.

VERSIONS:

• workspacesclient version: 4.0.1.1302
• OS version: Ubuntu 20.04.3

I tried the following:

• uninstalling and reinstalling the workspaces client: no change

• mv ~/.cache/workspacesclient{,.$(date +%Y%m%d.%H%M%S)}: launching does not create a new one, and no running client either.

• mv ~/.local/share/Amazon\ Web\ Services{,.$(date +%Y%m%d.%H%M%S)}: launching brings a popup that prompts me to enter my registration code, and then disappears. There is a new ~/.local/share/Amazon Web Services, but no running client.

• I looked at the most recent log files in ~/.local/share/Amazon Web Services/Amazon WorkSpaces/logs, but nothing was obvious to me.

I can connect to this workspace from other computers, so the workspace itself seems to be fine.

Please help me recover the use of the workspaces client on this computer.

Thanks!
