On OS X Catalina, running 'solve' in DifferentialEquations causes crash

General Usage
23 
julia> versioninfo(); VectorizationBase.REGISTER_COUNT
Julia Version 1.4.2
...
16

julia> versioninfo(); VectorizationBase.REGISTER_COUNT
Julia Version 1.6.0-DEV.306
...
16

Just to note the following happened while I was getting 1.6 ready to run this:

julia> import VectorizationBase
ERROR: ArgumentError: Package VectorizationBase not found in current path:
- Run `import Pkg; Pkg.add("VectorizationBase")` to install the VectorizationBase package.

Stacktrace:

No Changes to `~/.julia/environments/v1.6/Manifest.toml`

VectorizationBase was definitely on board earlier this evening when I ran the update. Might not be relevant, but I thought I’d mention it.
