I2cdetect -y 1 problem

Hardware
1

I have a problem with my i2c and some components

When I use the command i2cdetect -y 1 i see

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --

With every symbol taking 1 second after each other to show up. It almost looks like a loading screen...
my BME280 sensor does not show up when I use the command.

I have a backup SD with a previous version of my flows etc. somehow, when i don't change the hardware and wiring but only swap out the SD the command i2cdetect -y 1 does pop up at once and I see my BME280 address instantly.

Could anyone help me with why one SD could and the other couldn't locate the i2c address?

NPM 6.14.16
JSON 14.19.0
Node Red 3.0.2
versions are equal between the backup SD and my current SD

Are the two SD cards using different OS versions?
On the SD card that doesn't show any addresses, did you turn enable I2C in the raspi-config item 3 (Interface Options)?

I did!

Both Rasbian. Not sure which version tho! Is that of significance?

could be, run the following command cat /etc/os-release will give you something like this:

pi@argonpi:~ $ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

It says 10 buster on both SD's

I would try on the SD card with the issue
sudo apt update
sudo apt full-upgrade -y
and then try the i2cdetect -y 1

You should open a thread on the raspberryPi foundation’s forum
