Rebuilding GUID cache: Deleting metadata Packages/com.unity.purchasing/UnityEngine.Purchasing.dll because the asset doesn't exist anymore. MetaData path library/metadata/b5/b5f4343795a0e4626ac1fe4a9e6fce59

这是Unity中的一个日志信息，指出正在重建GUID缓存，并删除了指向不存在的资源的元数据。具体来说，它删除了路径为"library/metadata/b5/b5f4343795a0e4626ac1fe4a9e6fce59"的元数据，该元数据对应于Packages/com.unity.purchasing/UnityEngine.Purchasing.dll这个资源。

这个信息通常不是一个错误，而只是Unity编辑器在进行一些清理工作时的输出。当Unity发现某个文件被删除或移动后，会尝试删除对应的元数据，以避免这些废弃的元数据占用过多的空间或者影响下一次的构建。因此，这个信息的出现通常是正常的，可以忽略它。

interworking not enabled. first occurrence: ./Proj/BootTask/Bootloader.o: Thumb call to ARM

This error message suggests that there is a problem with the interworking between Thumb and ARM code in the project. It may be caused by a mismatch between the compiler settings or the code itself.

To resolve this issue, you can try the following steps:

1. Check the compiler settings and make sure that the interworking feature is enabled. This setting should be enabled by default in most compilers.

2. Check the code and make sure that there are no incompatible calls or jumps between Thumb and ARM code. You can use the disassembly view to inspect the code and look for any instructions that may cause interworking issues.

3. If the problem persists, you can try rebuilding the project with different compiler settings or using a different compiler altogether.

It's also possible that this error message is just a warning and doesn't actually affect the functionality of the project. If the project is working as expected, you can ignore this message. However, it's always a good idea to investigate any error messages to ensure that your code is functioning as intended.
