Checklist

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

As requested here.

On a fresh install, the "Check for Update" button will cause a crash due to the updateChannel value being blank.

This is due to the updateChannel value having no default value (https://github.com/shadPS4-emu/shadPS4/blob/main/src/common/config.cpp#L46). When a new config file is generated on a fresh install, it's generated without this default value. See the file diff below:

$ diff -r broken-install/ working-install/
Only in working-install/user: addcont
diff -r broken-install/user/config.toml working-install/user/config.toml

< isPS4Pro = false
< BGMvolume = 50
< logFilter = ""

< logType = "async"

---
> mw_width = 1280
56a53,55
> geometry_x = 276

< sliderPosGrid = 0
< geometry_x = 323
< gameTableMode = 0
---
> installDirs = ["F:\\Documents\\Emulators\\ISOs\\PS4"]
> addonInstallDir = "F:\\Documents\\Emulators\\ps4-back\\user\\addcont"
63c62
< geometry_y = 139
---
> geometry_y = 103

> emulatorLanguage = "en"

This seems to be because the function which would set this value (https://github.com/shadPS4-emu/shadPS4/blob/main/src/common/config.cpp#L46) is only called when you hit the "Restore Defaults" button.

Mitigation Steps

You can fix this by opening the settings and clicking "Apply". As an update channel is selected by default, it will save the config file with the selected value (instead of being blank).

Reproduction Steps

Delete your existing config file.
Open the application.
Click the "Check for Updates" button

Expected Behavior

The config file is generated with a default value for the updateChannel value.

Specify OS Version

Windows 10

reading the log you posted you are using a fork of shadPS4 (PartBB) , your bug can not be reproduced on main emu so i suggest you use the official builds.

Whoops - my bad. I thought I had double checked to make sure this was reproducible on the latest pre-release version back when I first made my comment.

I should've also double checked to make sure that it was still applicable on the newest release (this was done about a month ago, after all).
