Error Importing Wallet File

**Describe the bug**
When I updated my Specter all my utxo labels disappeared. But I do have the specter-backup as well as the wallet json backup. When attempting to import the wallet json backup with the "import from wallet software" in add new wallet, I get the following error: " Unsupported wallet import format:Invalid \escape: line 1 column 526(char525)"

**To Reproduce**
Steps to reproduce the behavior:
1. Go to 'add new wallet'
2. Click on 'import from wallet software'
3. Choose file
4. Import wallet_name.json file
5. Error

**Expected behavior**
My old wallet and labels to be imported

**Desktop (please complete the following information):**
- Where is your node running: local(internal)
- Where is your specter running: binary I think
- If you're running a binary, which OS: Windows
- Specter Version 1.13.1

Reproduce the failure on Windows using the reported wallet_name.json through Add New Wallet and “import from wallet software.” Trace the wallet JSON import path from that UI entry point and identify how the reported invalid escape is handled. Done means the backup imports successfully and the old wallet labels are restored.
