1.6.4 Does Not start: Cannot get/create entry with parent path [cache] because of an incompatible intermediary value of type

[tbenr]

Describe the bug
when running java -jar librespot-player-1.6.4.jar it doesn't start even with freshly generated config.

1.6.3 works instead (same config)

my java version:

openjdk 21.0.4 2024-07-16
OpenJDK Runtime Environment (build 21.0.4+7-Ubuntu-1ubuntu224.04)
OpenJDK 64-Bit Server VM (build 21.0.4+7-Ubuntu-1ubuntu224.04, mixed mode, sharing)
