Coldcard plugin not working after CKCC-PROTOCOL upgrade to version 1.5

[bitcoinlizard]

Description

The CKCC protocol recently upgraded from version 1.4.0 to 1.5.0:
https://github.com/Coldcard/ckcc-protocol

I am running Electrum 4.6.2 on Archlinux.

Since the upgrade I get an error when trying to use a wallet with a Coldcard as a signer:

With the working 1.4.0 version of CKCC this is how my startup looks:

$ QT_QPA_PLATFORM=xcb electrum
qt.qpa.services: Failed to register with host portal QDBusError("org.freedesktop.portal.Error.Failed", "Could not register app ID: Unable to open /proc/53862/root")
qt.qpa.theme.gnome: dbus reply error: [ "org.freedesktop.DBus.Error.AccessDenied" ] "Portal operation not allowed: Unable to open /proc/53862/root"
qt.qpa.theme.gnome: dbus reply error: [ "org.freedesktop.DBus.Error.AccessDenied" ] "Portal operation not allowed: Unable to open /proc/53862/root"

The little Coldcard icon is present in the lower right.

With the broken 1.5.0 version of CKCC this is how my startup looks when opening a wallet with a Coldcard signer:

$ QT_QPA_PLATFORM=xcb electrum
qt.qpa.services: Failed to register with host portal QDBusError("org.freedesktop.portal.Error.Failed", "Could not register app ID: Unable to open /proc/53422/root")

The little Coldcard icon does not show in the lower right.

There doesn't appear to be a CKCC_SIMULATOR_PATH module in ckcc-protocol.

Thanks for the report.
That minor rename seems to be the only breaking change in ckcc-protocol 1.5.0. (though I could not find release notes -- I skimmed the diff instead)
