これは私のアドオンではないので、とても異例ですが、コメントしておきます。
結論的には、このエラーの発生箇所のIsInUIというAPIは、
Update43までのパッチリリースのどこかでプライベート関数から通常の関数に属性変更される予定になっています。
よって、このUIエラーは特にアドオンで対処しなくても、いずれ発生しなくなる。
端的にいうと、アドオン側でできる対策はないということ

it is by BugCather report.
If I use J2Eupdate, it happened.

DailyProvisioning not working for game controllers. Help please...(assuming your library could fix it)

The new version version DailyProvisioning 1.4.16 is fixed

LibStub is not used within this library.

@Marify
Please remove the line in your LibMarify.txt file:
## OptionalDependsOn: LibStub

and everything should be okay.

Hello, and thanks for your addons! I especially like Confirm Master Writ

Could you please do away with any/all references to LibStub in this library and your other addons?

LibStub's author has declared it not proper usage any longer and is now nagging me in chat. Thank you!
