I cannot package my plugin in 5.1 for Android (missing precompiled manifest for 'Launch')

I have been developing a plugin for a while now that is compatible with several versions of the Unreal Engine. I’m trying to port it to Unreal Engine 5.1 but I have a problem when I try to package my plugin and I can’t find a solution. Here is the error:

Compile module: Launch
Missing precompiled manifest for 'Launch', 'P:\UNREAL\UE_5.1\Engine\Intermediate\Build\Android\arm64\UnrealGame\Development\Launch\Launch.precompiled'. This module was most likely not flagged for being included in a precompiled build - set 'PrecompileForTargets = PrecompileTargetsType.Any;' in Launch.build.cs to override. If part of a plugin, also check if its 'Type' is correct.

At no time in my code do I refer to the Launch module. I can package for Android my sample project that uses my plugin without any problem.

Also I have no problem with previous versions of the Unreal Engine. My plugin is already available for Unreal Engine 4.26, 4.27 and 5.0
Do you have an idea to solve this problem? Thanks

Ok it looks like this is a known bug and will be fixed with version 5.1.1

It never got fixed. Can’t package to Android if DLSS plugin is enabled. Always give the manifest error. I sent the log to ChatGPT and it couldn’t fix it either. Nor can find a solution online.
