Wow, that’s a lot. Must be a new channel creation type thing or something? I’m not 100% sure about the cashu protocol and how it all interfaces with lightning.

I'm assuming it's the new channel creation but it still seems high for a base chain fee

The mint can set any amount it wants i guess to redeem. This is just another way they can scam ya.

I wouldn't rush to blame the mint without more info. Sounds like a lightning wallet setup issue.

Don't use eNuts it isn't maintained. Use cashu.me or @Minibits . Sounds like you are trying to open a channel with the token. Cashu doesn't take fees to redeem. There are fees to send a lightning transaction however.
