Bug? Error In Release Mode: "typeerror: E Is Undefined"

I'm having an issue releasing my game. When I have it my Build Configuration set to Release, my game doesn't work properly.

I am given a series of errors in the console:

Code (JavaScript):

1. TypeError: asm.js type error: Disabled by debugger game.js
2. TypeError: e is undefined[Learn More] 5:263:352
3.     <anonymous> (index):263
4.     <anonymous> (index):262
5. TypeError: Module._main is not a function[Learn More] 1:12:690
6.     callMain (index):12
7.     e (index):12
8.     main (index):12
9.     <anonymous>

It runs perfectly fine when Build Configuration is Development. Additionally, when I host the "Development" build on a web server, I'm given this error:

Code (JavaScript):

1. TypeError: vegabyte.rascaille.client.GameManagerSystem is not a constructor[Learn More] main.js:27:60
2.     main http://127.0.0.1:5500/src/main.js:27
3.     run http://127.0.0.1:5500/src/runtime.js:142752
4.     adMain http://127.0.0.1:5500/src/runtime.js:143141
5.     main http://127.0.0.1:5500/src/runtime.js:142756
6.     <anonymous> http://127.0.0.1:5500/src/index.html:14

Am I doing something wrong?

 

This seems to only happen when I'm using an external library, like this thread suggests: https://forum.unity.com/threads/can-the-typescript-engine-run-regular-javascript-code.594064/

It's curious that it only breaks in Release, but not in Develop.
