Upload sketch with SerialUPDI HV Programmer doesn't work

Hi,
I'm working on a new description of how to burn the bootloader:
https://avdweb.nl/arduino/attiny3217/bootloader-attiny3217
I have a problem with the megaTinyCore version 2.6.10 and the SerialUPDI_HV_Programmer
The used SerialUPDI HV Programmer is this:
https://github.com/wagiminator/AVR-Programmer/tree/master/SerialUPDI_HV_Programmer
This works well: I can upload sketches with the SerialUPDI HV programmer, with the high voltage pulse disabled to an new and unused ATtiny3217.
Problem:
Uploading sketches with the 12V pulse enabled, gives an error message, see below.
Can you try to upload a sketch to a new and unused ATtiny3217 with the 12V HV puls enabled?
Maybe it is necessary to first burn the bootloader (UPDI=UPDI, not reset pin) before being able to upload a sketch with HV pulse? The bootloader is maybe just needed to configures some fuses?
Note that, in the year 2020, I had successfully worked with the megaTinyCore and I was able to upload sketches via UPDI and also via the burned bootloader.
Arduino settings:
Scope
Error messages
without HV pulse OK.txt
May be the timing is too tight between pulse and prog?

Maybe, but I cant do anything about it, it is controlled by the megaTinyCore and the Arduino IDE.
