Here are a few steps you might consider to address the issue:
Backup: Before attempting any fixes, make sure to create a backup of your wallet file. This ensures that you don't lose any data in case something goes wrong during the troubleshooting process.
Update Electrum: Ensure that you're using the latest version of Electrum. Sometimes, software updates include bug fixes that could resolve parsing errors or other issues.
Check File Integrity: Verify the integrity of your wallet file. It's possible that the file became corrupted, leading to the parsing error. You can try using file recovery tools or utilities to repair any corruption.
Recovery Options: Since you have the password, you may still be able to recover your funds even without the seed. Consider reaching out to Electrum support or consulting with cryptocurrency experts for guidance on potential recovery options.
