Your input is not a valid ICS file (note END:VEVENT before START:VEVENT and SEQUENCE outside any object). As such, you cannot use an ICS parser. Depending on where you got this file, and whether its consumer expects ICS or this broken ICS-adjacent format, you may want to invest in fixing the file.
To just strike the subject can simply use a regular expression though:
import re
with open('test.ics', 'r', encoding='utf-8') as icsf:
broken_ics = icsf.read()
out = re.sub(r'\nSUMMARY:(?:.*(?:\n )?)*', '', broken_ics)
print(out)
