New type Stash for Block is not a mixin type

Hello,

Since I upgraded to the last Rakudo I'am having a weird problem. I have a
module like this:

unit class Class1;
etc.

Then a second module:

unit class Class2;
use Class1;
etc.

In a program I need both modules, so it begins with two lines:

use Class1;
use Class2;
etc.

At this point if I run the program I get this error:

New type Stash for Block is not a mixin type

pointing to the line of code that uses Class2. If I remove the "use Class1"
line, that program works fine.
But it bugs me, because I don't understand that behavior.

Any hint?
The whole thing worked fine using version 2020.07.
