Why does @typescript-eslint cache old types/files and fail to compile?

I start my Typescript application with tsc -b -w and am consistently finding that @typescript-eslint does not respond to file changes correctly. It will report invalid types/syntax where no problems exist. Sometimes, even restarting the process does not fix the problem. The only way to fix it is to make whitespace edits to the file and save again, hoping that this time things work.

Example

I just created an interface in ./types.ts:

export interface IHaveWorkspace {
  workspace: Workspace;
}

I then import and attempt to use this interface in index.tsx. However, when I attempt to access myObj.workspace, I get the following errors:

[1] src/components/Navigation/index.tsx
[1]   Line 26:29:  Unsafe assignment of an any value                @typescript-eslint/no-unsafe-assignment
[1]   Line 26:29:  Unsafe member access .workspace on an any value  @typescript-eslint/no-unsafe-member-access

Notably, it is not complaining about the interface itself. It seems unable to understand the interface's types, but it does not raise any other errors (e.g., importing the interface). Saving the files and even restarting the process have no effect. Eventually, after making whitespace changes and saving some more, the errors magically go away.

Config

FWIW...

.eslintrc.js:

module.exports = {
  root: true,
  parser: '@typescript-eslint/parser',
  plugins: ['@typescript-eslint', 'eslint-plugin-react', 'eslint-plugin-react-hooks'],
  extends: [
    'plugin:@typescript-eslint/recommended',
    'plugin:@typescript-eslint/recommended-requiring-type-checking',
    'prettier',
    'prettier/@typescript-eslint',
  ],
  rules: {
    'indent': ['error', 2],
    'linebreak-style': ['error', 'unix'],
    'quotes': ['error', 'single'],
    'semi': ['error', 'always'],
  },
  env: {
    amd: true,
  },
  parserOptions: {
    project: './tsconfig.json',
    tsconfigRootDir: __dirname,
  },
};

And tsconfig.json:
