[Bug]: T-Beam Supreme - Display stays black

Display not working - stays black

Hardware

LilyGO T-Beam Supreme U-blox MAX-M10S

Firmware Version

2.1.11.5ec624d

Description

The OLED Display (SH1106 - I2C connected to SDA:1017 / SCL:1018) stays black
Using SoftRF the display works fine
I re-flashed several times (also with the "core-board" disconnected from the "body", using CLI ((“./device-install.sh -f firmware-tbeam-s3-core-2.1.11.5ec624d.bin”) and the web-interface.
Watching the log I noticed a 2 minute pause after "Scanning for i2c devices on port 1". When the "core-board" is disconnected from the "body" there is no pause.
Also setting the display manually to SH1106 does not cure the problem.

Relevant log output
