Error: Debug Failure. False expression: Non-string value passed to ts.resolveTypeReferenceDirective, likely by a wrapping package working with an outdated resolveTypeReferenceDirectives signature. This is probably not a problem in TS itself.

Update: the error is probably only caused by a human error (mixing npm and yarn), but anyway, we should check if updating typescript version works.
