That's really strange to hear, I've run it in on a pi zero, until it died, a 4b, and now on a pair of orange pi zero 2 I think they are, without any issues I didn't directly cause by computing drunk.
I'd give it another shot if you're up for it, it's worth it in my opinion. I'm also running wireguard on it, with clients on all our phones so we take that protection with us everywhere.
