Deep Sleep Touch Wake stops working on Tool Chain update from v3.0 to V3.22

Hello,
The following code is from my esp32 application which goes into deep sleep and will wake on either a Left / Right Touch, or from the Timer. This is working code that has been running for over a year on previous tool chain versions; most recently V3.0.

Today I upgraded my toolchain to V3.2.2 and recompiled / flashed. Everything seems to work correctly and enters deep sleep mode; however the Touch wake feature no longer works. The timer wake does.

Is there a MenuConfig parameter that I have not set or some new function that is also required to enable touch wake from deep sleep?
Thoughts??

<<<code section - prepare and enter deep sleep

SENS.sar_touch_enable.touch_pad_worken = 0; //this keeps the sleep touch from stimulating all rtc touch pins
touch_pad_init();
touch_pad_config(TOUCH_PAD_NUM5, 0); //Right Touch Off
touch_pad_config(TOUCH_PAD_NUM6, 0); //Left Touch Off
touch_pad_clear_status();

touch_pad_set_voltage(TOUCH_HVOLT_2V4, TOUCH_LVOLT_0V8, TOUCH_HVOLT_ATTEN_0V);
touch_pad_set_meas_time((uint16_t) 20000, (uint16_t) 2048);

touch_pad_config(TOUCH_PAD_NUM5, R_Threshold); //Right Touch Sensitivity
touch_pad_config(TOUCH_PAD_NUM6, L_Threshold); //Left Touch Sensitivity
esp_sleep_enable_touchpad_wakeup();

printf("Enabling timer wakeup, %dS\n",wakeup_time_sec);
esp_sleep_enable_timer_wakeup((uint64_t)(1000000 * (uint64_t)wakeup_time_sec));
vTaskDelay(100 / portTICK_PERIOD_MS);

//Setting deep sleep power down options
esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_SLOW_MEM, ESP_PD_OPTION_AUTO);
esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_FAST_MEM, ESP_PD_OPTION_AUTO);
esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_PERIPH, ESP_PD_OPTION_AUTO);

printf("Entering Touch / Timer deep sleep\n");
esp_deep_sleep_start();
