Apple Store Clozure doesn't start under OSX 10.15.1

On Catalina 10.15.3, startup of Clozure 1.11.7 is very unreliable. Sometimes it starts and runs fine. Most of the time it gets into the following error right away.

> Error: #<A Foreign Pointer #x409060> has no slot named GUI::PEER.
> While executing: #<CCL::STANDARD-KERNEL-METHOD SLOT-MISSING (T T T T)>, in process Initial(0).
> Type :POP to abort, :R for a list of available restarts.
> Type :? for other options.
1 > 

Recovery is possible with :Q in that case.

I have nothing to add, other than to report the same error as clarino. On my last successful startup, I got a Listener, could create a file, but when I cancelled the Save, this:

Unhandled exception 4 at 0x7fff6f0f548e, context->regs at #x7ffeefbfe310 Exception occurred while executing foreign code at _os_unfair_lock_corruption_abort + 23 ? for help [18273] Clozure CL kernel debugger:

Sadly, the Mac App Store version of CCL is broken and no longer available.
