I don’t know the specifics behind why the limit is 72 bytes, but that might be slightly tricky. My understanding of bcrypt is that it generates 2^salt different possible hashes for the same password, and when you want to test an input you have to hash the password 2^salt times to see if any match. So computation times would get very big if you’re combining hashes
bcrypt has a maximum password length of 72 bytes.

While you didn’t name names of what app you were using for streaming, I just got into a similar situation with my dorm and what I found worked was using wired ALVR for my streaming. Not wireless, but good, long right-angled USB-C cables don’t cost a fortune. https://github.com/alvr-org/ALVR/wiki/ALVR-wired-setup-(ALVR-over-USB)
