There already are quite some suggestions in this thread. Did you read them all and try to understand?
Without seeing the actual VI (preferably backsaved to 2019 or earlier) and yes the VI itself not just a screenshot, we can only simply go and repeat everything that was already said, which I’m to lazy to do.
Maybe one more suggestion. Watching this video shows you most if not all gotchas that most users run into when talking to serial devices: https://labviewwiki.org/wiki/VIWeek_2020/Proper_way_to_communicate_over_serial
It must be already the most quoted link in this forum. If Tim got one cent for every quote and person clicking on that link he would be a millionaire! And if you haven’t seen this mentioned somewhere while researching your serial communication problem, your Google foo is seriously lacking.
