Error: This expression has type prefix:string -> bool
       but an expression was expected of type 'a -> bool

This error occurs when building on both Windows and Linux, and occurs for me both locally and when building via Github Actions, on commit ID 760c0dd, which is the tag of the 4.3.6 stable release.

Since the branch itself has not changed, I believe that this error may be a result of some dependency library not being locked properly.
