I'm building a simple project that uses the VL53L0X distance sensor as input to turn on an RGB LED strip. As I draw my hand back away from the sensor, gradually more lights illuminate along the strip until finally, at a certain distance, the rainbow() function from the Neopixels strand test is called. This is where I run into a problem as the rainbow animation displays but it causes everything to crash and stop responding to input. At first I thought this was because the VL53L0X main function to check distance operates with a call for a delay() function as does the rainbow() function so calling one from the other must be messing it up. So I found an example using millis() and comparing the start time to a desired interval and implemented that instead but it still crashes. Any ideas on how to fix this or is it just not possible?
It will be hard to say what might be wrong with the sketch without seeing it.

Its a bit of a Frankenstein's monster as I'm still new to this so please be kind

This forum IS kind. If somebody woud post something unfriendly this person receives a warning or a temporary ban from the forum.
A good way to learn how to code is to get feedback what can be improved.
as a short hint (which is too less to be really instructive)
Your code has a lot of similiar lines.
You can use parameters and you can use arrays to shorten your code.
parameters are something that will take 1 to 3 hours to understand.
arrays will take 1 to 3 hours too.
You should
explicitly NOT
apply parameters and arrays immidiately to your code
You should learn the basic principles with small demo-codes.
Believe me than it will take you 1 to 3 hours.
If you try to apply it after 10 minutes reading to your code you will mess around with bugs for ten times long 10 to 30 hours.
I recommend that you work through this tutorial
Arduino Programming Course
It is easy to understand and has a good mixture between explaining important concepts and example-codes to get you going. So give it a try and report your opinion about this tutorial.
How many neopixels are in line on one IO-pin. If you are below 250 per IO-pin you can put them all on one dataline and use an offset for accessing the next part
