React Native - Constant errors like "Error: EPERM: operation not permitted, lstat ..."

Question

I am fairly new to React Native, and it appears my app is crashing prior to executing my primary app code, but I cannot figure out where. In VSCode, I see the following in my Output:

Error: EPERM: operation not permitted, lstat 'c:\Dev\myapp\android\app\build\generated\not_namespaced_r_class_sources\debug\r\com\bumptech\glide\integration\okhttp'
Emitted 'error' event on NodeWatcher instance at:
    at NodeWatcher.<anonymous> (c:\Dev\myapp\node_modules\sane\src\node_watcher.js:291:16)
    at FSReqCallback.oncomplete (fs.js:176:21) {
  errno: -4048,
  code: 'EPERM',
  syscall: 'lstat',
  path: 'c:\\Dev\\myapp\\android\\app\\build\\generated\\not_namespaced_r_class_sources\\debug\\r\\com\\bumptech\\glide\\integration\\okhttp'

I'm trying to figure out how to determine where this is coming from, and how to debug errors like this in the future.
