This is a duplicate of bpo-45924. The traceback accumulates another frame
every time the exception is raised. To see that, change main in your script to
async def main():
task = asyncio.create_task(task_that_raise())
while True:
try:
await task
except Exception as e:
print("<<<<<<<<<<<<<<<<<<<<<<<<<<<")
traceback.print_exception(e)
print(">>>>>>>>>>>>>>>>>>>>>>>>>>>")
and notice that in the output, X grows every time in the line like
[Previous line repeated X more times]
