Keep the mapping-argument setup non-blocking.
OnPreprocessBuild calls Directory.CreateDirectory, File.WriteAllText and PlayerSettings.SetAdditionalIl2CppArgs without a guard. In Unity, an exception thrown from IPreprocessBuildWithReport stops the build. A trigger is a Library/Bugsee path that cannot be written, for example because of permissions or a locked file. In that case an optional symbol feature fails the player build. Put the setup in a try/catch block. On failure, log a warning and continue without the arguments.

Keep the pending restore when SetAdditionalIl2CppArgs fails.
ResolvePending catches a restoration exception, then deletes PendingPath. The applied flags can remain in Player Settings, and the editor-startup retry cannot run because the pending file is gone. The update handler is also removed before this call. Preserve the pending record when deserialization succeeded so a later editor session can retry.

Problem
The il2cpp-linemap upload of an Android build carried no
MethodMap.tsv, so mangled managed names could not be demangled (UNITYTA-19). Without--emit-source-mappingthere was noLineNumberMappings.jsoneither.Root cause
IL2CPP writes
Symbols/LineNumberMappings.jsononly with--emit-source-mappingandSymbols/MethodMap.tsvonly with--emit-method-map(Unity itself adds the first on 2022.3/6000 only when Cloud Diagnostics crash reporting is on). The package never passed either argument; the sample project set only--emit-source-mapping, which hid the gap.Evidence:
EmitSourceMapping,EmitMethodMapinUnity.IL2CPP.dll);--emit-source-mapping:Symbols/hasLineNumberMappings.json+il2cppFileRoot.txt, the upload logshas_method_map=false; adding--emit-method-mapproduced a 24,568-lineMethodMap.tsvandhas_method_map=true;bugsee-clialready packs a siblingMethodMap.tsv(dry run), so the upload code needed no change.Fix
Editor/BugseeIl2CppMappingArgs.csadds--emit-source-mapping --emit-method-mapto the Additional IL2CPP Arguments for Android/iOS/tvOS IL2CPP builds when the il2cpp-linemap upload is on (app token set,BUGSEE_NO_IL2CPP_MAPPINGunset, no explicitBUGSEE_IL2CPP_MAPPINGfile), and restores Player Settings afterwards. The restore also runs after a failed or cancelled build (one-shot editor update handler; the post-build callback is skipped when the pipeline aborts), with the saved state inLibrary/Bugsee. A string you edited meanwhile is kept and logged. Policy is inRuntime/WrapperPolicy(Il2CppMappingArgs,Il2CppArgsRestorePolicy) with tests. Stale guidance in docs, the linemap warning and the sample'sE2EBuildis updated.Verification
PlayerSettings.Get/SetAdditionalIl2CppArgs).ProjectSettings.assetclean,Library/Bugsee/il2cpp-args-restore.jsongone),MethodMap.tsvandLineNumberMappings.jsonproduced, uploaded withhas_method_map=true(2021.3 writes noil2cppFileRoot.txt, which is optional).Limitations
