Steps to reproduce
I installed the latest version of pwsh using the command "winget install --id Microsoft.PowerShell --source winget". However, this issue occurs every time a new version of pwsh is released on my computer. When I reinstalled the latest pwsh using the command "winget install --id Microsoft.PowerShell --source winget", pwsh could open normally again. But the same problem would occur again when a new version was released.
Expected behavior

Your image shows this is running in 7.6.6.
This issue has been fixed in 7.6.8 onwards by the removal of the code that provided the update notification during startup.
You can get round this in 7.6.6 by setting the documented env var
POWERSHELL_UPDATECHECKtoOFFand then upgrading PowerShell.lzb-libra commentedon Nov 3, 2026
The version number in my picture is 7.6.6 because I forgot to take a screenshot at that time, so I used the screenshot from an earlier version. When I opened the local 7.6.8, the same problem occurred, preventing me from using it. Then, I installed the latest version 7.6.9 using the command "winget install --id Microsoft.PowerShell --source winget" and it worked properly. I won't change the configuration you mentioned for now and will observe one version to see if the problem persists.
