Other times I've seen this error that cause was an environment variable with non-ASCII or non-UTF-8 characters in it or something like that. Do you have admin access to the server to check?

That’s pretty unusual, especially since you’re encountering this on different machines; maybe it’s something being provided by your AD domain or other Windows setup? If the Ubuntu install has a desktop environment, you could try launching a designer there. You can see the names and values of the default environment variables on Windows pretty easily: [https://ww…](https://www.architectryan.com/2018/08/31/how-to-change-environment-variables-on-windows-10/)
