Patching impossible because of pending update (Sonoma, MacPro 3.1 OCLP 2.40)

After updating to Sonoma 14.7.8 I have immediately done a Root Patching - working fine.

But an updater for Sequoia was loaded later in the background. Because I do not want to update to Sequoia then I changed the update settings and the updater for Sequoia was not displayed anymore.

Then I later discovered that Root Patching failed - see above screenshot.

Searching reddit and the net I came across earlier reports about this, but no real solution.

I do not see any installer in the application folder and OCLP 2.40 does not find any installer when trying t create an installer using "existing installer".

Searching my harddisk for "Sequoia" the only thing a find is an older com.apple.sequoia.asset.plist file from the day when I created an Sequoia install stick for another computer.

How can I get rid of this issue ?
