svn password prompt hanging in PowerShell

Sorry, just to clarify.. I just tried using cmd.exe and that had the same
problem - so not just a PowerShell problem.

Running Windows 10 1803 (17134.112)

I downloaded the latest TortoiseSVN build along with debug symbols and got

My AD domain password changed recently, and so running 'svn update' is
now prompting me to enter my new password.
If I run this from the PowerShell command prompt, I enter the first
character of my password and then the UI locks up.
eg.
D:\dev\svn\MyProject> svn update
Authentication realm: <https://svn.server.com:443> SVN Server
Password for 'dgardiner': *
A colleague has had the same experience. His workaround was to use
cmd.exe instead of PowerShell.
This used to work without issue. Not sure if it's a change in svn.exe or
PowerShell.

Can you try another binary distribution, for instance
https://www.visualsvn.com/downloads/ ?
Just to rule out that it's related to one particular binary package / build.

I downloaded the visualsvn build as suggested, and that appears to work
without issue
Using the tortoisesvn svn.exe, I also had a merge conflict while running
'svn update' and the prompt for resolve the conflict also hung (so looks
like it's a general problem with user input, not just related to passwords)

Okay. In that case, please report this problem to one of the
TortoiseSVN lists: https://tortoisesvn.net/community.html

It appears to be something specific to their build.

Thanks! That's very useful information. Let's hope MS will fix this soon.

Just circling back with an update. The Tortoise folks discovered this is a
bug in a library that shipped in Windows 10 RS4, possibly related to VS2017.
See
https://developercommunity.visualstudio.com/content/problem/245451/unbuffered-console-io-is-broken-only-in-release-bu.html
As such I suspect it will probably affect other distributions if they use a
similar build tool chain.
