CredentialUIBroker.exe freezing while accessing Brave Browser password manager

[pulsarclarinetokrabee]

Describe what you noticed and did

1. Open Brave sandboxed
2. Open the Password manager (brave://password-manager/passwords)
3. Click add, then create an arbitrary password entry and save it
4. Click on the newly created entry, a Windows Safety dialog (CredentialUIBroker) should open asking for authentication
5. Upon clicking OK or trying to close the window, the dialog will freeze. Thus the editing the saved Brave passwords is not possible. The CredentialUIBroker has to be force closed

How often did you encounter it so far?

Always

Expected behavior

The authentication should behave the same as an unsandboxed Brave session.

Affected program

Brave Browser Version 1.65.123 Chromium: 124.0.6367.91 (Official Build) (64-bit)

Download link

https://laptop-updates.brave.com/download/BRV002?bitness=64

Where is the program located?

The program is installed only outside the sandbox.

Did the program or any related process close unexpectedly?

Yes, it did, but no .dmp file has been created in the system.

Crash dump

No response

What version of Sandboxie are you running now?

Sandboxie Plus 1.13.3

Is it a new installation of Sandboxie?

I have been using the same version for some time.

Is it a regression from previous versions?

Unknown. On Previous versions of Brave and Sandboxie it used to work, however it has been too long to pin point when the problem first started.

In which sandbox type you have this problem?

In a standard isolation sandbox (yellow sandbox icon).

Can you reproduce this problem on a new empty sandbox?

I can confirm it also on a new empty sandbox.

What is your Windows edition and version?

Windows 11 Pro 23H2 64bit

In which Windows account you have this problem?

A local account (Administrator).

Please mention any installed security software

none

Did you previously enable some security policy settings outside Sandboxie?

No

I can't reproduce this problem on Windows 11 23H2 (Hyper-V) or Windows 10 22H2. Please try with the latest release version.

With version 1.13.7 the problem remains. Other than setting up the whole computer from scratch there aren't any other ways I can think of to find the cause.

[offhub]

Try using older versions and see if it works.
v1.12.9
v1.11.4

[pulsarclarinetokrabee]

Tried v1.11.4 and went as far back as v.1.6.4. No change.
