Keep in mind now TypeScript 3.6.4 is out. Still, it's ok to read below what wasn't really working.

TypeScript <= 3.6.3 presents this issue, Handle parentless nodes in isParameterPropertyDeclaration.

If you install 3.7 (dev or the new beta), it will compile fine.

For that use disableTypeScriptVersionCheck

"angularCompilerOptions": {
  "disableTypeScriptVersionCheck": true
},
"compilerOptions": {
