T7i is 7 years old and having issues, should I get it fixed, or upgrade?

I'm increasingly getting the Error 01 code (The communication between the camera and lens is faulty) with both my lenses, so I'm guessing it's the body. Removing the lenses and putting them back on helps for a few shots, but then it's back to the error.

It seems like I just bought that camera , but I bought it in 2017, so it's 7 years old. It's in great shape otherwise. Hardly any wear, but I've read that getting them repaired is expensive, so I'm wondering if I should bother, or just upgrade to a new one?

The cost to repair might be past the point of diminishing returns.  I recommend reaching out to Canon to get an estimate.  Ask about their upgrade program.
