Cannot flash ESP32 any more; error when calling

Since a few days suddenly i cannot upload builds to my ESP32 board.
I’m using PlatformIO on MS Visual Studio Code, Home 0.6.1 / Core 3.5.2a1, Platforms Espressif 32 0.11.0 and Espressif 8266 1.6.0.

Error log see below.

I tried a full fresh installation already - but no success. Any idea what to do?

Should be fixed in the latest version. Please try Espressif 32 — PlatformIO latest documentation

After switching to staging and doing all updates my PlatformIO IDE is working again.
Thank you very much for your help!
