we have been using the VL53L0X in commerical designs for many years.
Pololu - VL53L0X Time-of-Flight Distance Sensor Carrier with Voltage Regulator, 200cm Max
There are 2 large holes for mounting the VL53L0X.
Are the mounting holes connected to internal ground planes or traces of the internal PCB?
we are trying to analyze some new problems that have arisen

Hello.
I moved your post to a support category since it seems more appropriate there.
Those are mounting holes, and they are not electrically connected to any of the board’s routing. The design and manufacturing process for these carriers have not changed in any significant way since their release, so I would not expect you to start experiencing new problems with them now. Can you provide more details about the specific problems you are having and post some pictures of your setup?
