I have a cheap SOIC clip and sometimes need several attempts to make a good connection to the chip.
Are you correctly identifying the position of pin 1? I put a small dot of silver marker on the chip and clip to help me get them positioned correctly.
Pin one is near the triangle symbol on the ATtiny85 in your photo of your other D4 driver from your post in another thread.
FWIW, I’ve flashed five Emisars of various flavors without issue.
