V3.4.5 now causes boot loops on ESP32-P4 + C6, where V3.4.4 was stable

I just wanted to report this, but I am unsure what is causing the problem beyond the latest releases from V3.4.4 to V3.4.5 Everything has been stable with V3.4.4 after the 4096 memory allocation was changed to 4097. This change was reflected in V3.4.5 (thank you). However something else has been introduced which is now causing my ESP32-P4 to boot loop. Nothing else has changed other than this library. ESP32-P4 board/variant Arduino core 3.3.7 ESP-IDF 5.5.2 ESP-Hosted 2.11.6 Audio library 3.4.4 works Audio library 3.4.5 boot loops ESP32-audioI2S 3.4.4 works on ESP32-P4 (Arduino 3.3.7 / ESP-IDF 5.5.2 / PSRAM enabled). Updating to 3.4.5 causes an immediate boot-loop with assert spi_flash_disable_interrupts_caches_and_other_cpu ... esp_task_stack_is_sane_cache_disabled(). Reverting to 3.4.4 fixes it V3.4.5: ``` Rebooting...
