Doesn't close/exit/quit and freezes on multiple adb devices when none are selected.

[imrobbybobby]

Couldn't find an issue after an hour of searching so I'm making one now.

Environment

• OS: Windows 11
• Scrcpy version: 4.1
• Installation method: Tried Winget and Github release binaries
• Device model: Nothing Phone 2a/irrelevant
• Android version: 16

Describe the bug

Using scrcpy when multiple adb connections exist, hangs up the powershell window. CTRL + C does nothing and only way to regain access is to manually close scrcpy in task manager. I tried both the winget and github release. Same result, same with and without admin given to scrcpy. Happy to provide more logs if told how to access them. This started in v4.0 but i assumed it wouldve gotten fixed in 4.1 or that anyone else experienced it too.

Weird, I cannot reproduce.

Did you open by double-clicking on scrcpy.exe, or first started PowerShell then executed scrcpy?

If I open PowerShell and execute .\scrcpy (from the folder where scrcpy is installed), I get the error then a prompt (as expected).

If I run it by double-clicking on scrcpy.exe, it opens cmd.exe, and at the end, it prints "Press Enter to continue...".
If I open a cmd.exe terminal and execute scrcpy, I get the error then a prompt (as expected).

What is the result with:

scrcpy --pause-on-exit=false
scrcpy --pause-on-exit=if-error
scrcpy --pause-on-exit=true

?

Double clicking the exe does give a prompt to close the command prompt window that appears. Executing it in any terminal via command freezes it. Both Powershell and Command Prompt freeze if the command is used.

What is the result with:...

I get "Press Enter to continue..." when using --pause-on-exit=if-error and --pause-on-exit=true.
When using --pause-on-exit=false it stays open and ignores all input.

Executing it in any terminal via command freezes it. Both Powershell and Command Prompt freeze.

Even from cmd.exe?

If there is no error (only one device connected), does it terminate properly?
If you type an incorrect command (scrcpy --garbage), what's the behavior?

Yes, even cmd, same behaviour as PowerShell

If there is no error (only one device connected), does it terminate properly?

It closes properly and I have access to the terminal as expected.

If you type an incorrect command (scrcpy --garbage), what's the behavior?

It also closes properly and I have access to the terminal as expected.

I will setup a sandbox environment to see if it might just be my system somehow messing it up.

After testing it in a windows sandbox, it is indeed somehow exclusive to my system. It closes normally in the sandbox.

I shall attempt to return to usual behaviour somehow

UPD 1: Its localized to my user specifically, its fine on other users on the same system.
