Hi,
Recently I have come across these flow runtime errors. This host flow (not rfnoc) will generate and execute fine, but after sometime this error appears (baudline is never started):
-- [0/FIFO_0] sr_write(126, 00C1EA12, 0)
Traceback (most recent call last):

grc file and top_block attached. Any advise would be appreciated.
TIA,
