I was able to reduce this to the following repro (which is valid JS and can be run successfully):

const a = [3];
const b = [4];
const c = 0;
a[c] = b[0];
console.log(a);

Pasting this into the playground gives:

panicked at crates/biome_js_analyze/src/analyzers/correctness/no_self_assign.rs:716:18:

Which does seem to correspond to the error message:

biome/crates/biome_js_analyze/src/analyzers/correctness/no_self_assign.rs

Line 716 in 5dcae83

_ => unreachable!("you should map the correct references"),

Also getting the same error on following two lines:

let i = 0;
$myVar.TEMPLATE[i].LOCAL.test = $myVar.TEMPLATE[i].test;
