[Library agent] Failed to save updated preset 'Arnold UDIM Legacy (AiStandard)': The default library

Hello,

I am using version 10.1.2 and Windows 11.

When I try to export my textures it doesn't work, in the log says "[Library agent] Failed to save updated preset 'Arnold UDIM Legacy (AiStandard)': The default library 'starter_assets_1' is only available in read mode because you don't have write permission on it.". I want to export my textures in Arnold UDIM Legacy (AiStandard), exr 16 bits.

If someone can help me please, thank you.
