If I issue any build-related command in IDE (build, clean, upload), the core gets updated to 3.4.0a6 but then when I call serial monitor (still from within IDE), core gets downgraded to 3.3.0. Is there any way to pin core version so it does not do this dance? I have “use built in PIO core” set and I would like to still have it this way.
core: 3.4.0a6 (default)
Update: upload spiffs task (for ESP8266) downgrades core too.
