@Francois-Belanger It seems that the issue here is the one which is fixed by #3110 by adding a critical section, which prevents a level2 interrupt from occuring while a level1 interrupt is performing the frequency switch:

EPC1 : 0x40081d1c EPC2 : 0x40081d10 EPC3 : 0x00000000 EPC4 : 0x00000000
0x40081d1c: update_ccompare at /Users/ICE_Files/Firmware/esp/esp-idf/components/esp32/pm_esp32.c:426

0x40081d10: update_ccompare at /Users/ICE_Files/Firmware/esp/esp-idf/components/esp32/pm_esp32.c:426

Could you please try to apply the patch from #3110 and report if it fixes the issue you are observing?

pm: prevent interrupt nesting during esp_pm_impl_isr_hook
5328154 
Follows the approach proposed in #3110,
but masks the interrupts during the entire ISR hook, not only during
leave_idle. Interrupt nesting during update_ccompare may also cause
issues.

Closes #3057
