Printing multiple PDF's in multiple sizes failes

[Huffen]

Hi

Different errors appear, see below, and different results is achieved.
Sometimes I get one PDF created, sometimes none.
The issue is only in RVT 2019 and 2020. RVT 2018 works fine.
I have no idea of why it failes in 2019 and 2020, but works fine in 2018.

Following packages is used: Spring, Clockwork, Genius Loci and Archilab.
Setup to script:

Error 1:
Traceback (most recent call last):
File "string", line 139, in module
Exception: The iterator cannot proceed due to changes made to the Element table in Revit's database
(typically, this can the result of an Element deletion).

Result:
One PDF is printed.

Error 2:
Traceback (most recent call last):
File "string", line 152, in module
File "string", line 130, in PrintView
SystemError: attemted to read or write protected memory. This is often an indication that other memory is corrupt

Error 3:

Exception: The iterator cannot proceed due to changes made to the Element table in Revit's database
(typically, this can the result of an Element deletion).
