Can you add the code which triggered the issue? Thanks!

Not sure why the bug message isn't in the backtrace, but points to:

rust/compiler/rustc_middle/src/mir/interpret/queries.rs

Lines 98 to 106 in a4cedec

	// Cannot resolve `Unevaluated` constants that contain inference
	// variables. We reject those here since `resolve`
	// would fail otherwise.
	//
	// When trying to evaluate constants containing inference variables,
	// use `Infcx::const_eval_resolve` instead.
	if ct.args.has_non_region_infer() {
	bug!("did not expect inference variables here");
	}

Is the line mentioned CTFE related, or type check (const genetics?) related?
