Gradle 8 + R8 optimization result to an empty DB (or unreadable)

[nhsicot]

When I update my project to Gradle 8 (8.1.1) and use R8 optimization, paperDB is unsuable.
No error but nothing is stored in DB. (works fine in debug or without R8 optimization)
No problems with R8 optimization and Gradle 7 (7.5)

Any one else have this issue ?
Any plan to update PaperDb with a Gradle 8 compatibility ?
