BME 688 BSEC error code -34 on esp8266

Hello,

i had a working code of basic_config_state.ino running on Adafruit esp8266 board (programmed from Arduino IDE 2.3.3) doing coffee detection.
it was working ok, but then stopped predicting - showing only Fresh Air for everything.
I tried to download the latest binary from BOSH as well as latest libraries from GitHub, exported config from AI studio 2.3.4 and now after flashing i'm getting

BSEC error code : -34

(bsec2 lib version 1.8.261 as shown in IDE)

I tried to reset the board back to factory setting erasing all flash a few times, using:

python -m esptool --chip esp8266 erase_flash

but it still getting the same issue.

Can you please suggest a solution since it was the only board we were able to get AI feature semi-working with - it fails with various other errors on pretty much everything esle we tried (esp32's, M0+, M4) I found similar issue solved by using new board, which is not an answer /mems-sensors-forum-jrmujtaw/post/bme-680-bsec-error-code--34-GG4jucFuy7SHMUE?highlight=vySDXg3dH9nhd9G

Thank you
