"Internal Error" when launched from Finder, works from shell

Description

If Proxyman is started "as usual" via Finder/Spotlight, each and every connection fails with "Internal Error", Code 999 for unknown reason. There is no VPN active, proxy settings are correctly overwritten, no Little Snitch rule blocking it, certificates installed, valid & trusted. Factory reset did also not help.

In trying to debug the issue, I activated the debug log, quit Proxyman and started it from Terminal directly and lo and behold, it works just fine without any issues. Every time. Starting it via the app bundle from Finder does never result in a working Proxyman.

Steps to Reproduce

See above. Start from Finder -> Internal Error, 999 everywhere. Start from Terminal -> works.

Current Behavior

Every connection breaks with "Internal Error", 999 when started via app bundle. Works if binary started directly in Terminal.

Expected Behavior

Work regardless of the start method.

Environment

• App version: Proxyman 6.7.0 (trial)
• macOS version: latest 26.3.1 (a)

Reproduce the issue by launching Proxyman from Finder and then starting its binary directly from Terminal, with debug logging enabled. Compare the resulting logs and launch environments; done means connections work consistently through both launch methods without Internal Error 999.
