I2C device not found on address: 0x3C - on pi5

[dominch]

Hello

I can't run this lib on pi5 with SH1107 driver,
everything I try ends with error:

error: I2C device not found on address: 0x3C

in system I can easily run:

pi@pi5:~/luma.examples/examples $ i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

I double checked GND and other lines as in different ticket, all fine,
what else can I check - device is visible via i2cdetect but lib cannot access it,
i2c is of course enabled, user added to i2c group

it's plain 64bit rpi-os just burned for tests

Please show code where it is defined and then fails.
