Home Assistant preset errors

Had to restore backed up config & presets for a ESP32 WLED device that I accidentally flashed a ESP8266 firmware to. Reflashed over USB then reconfigured and HA is throwing a fit when I use presets. Saw reference to it likely being a corrupted preset json. Did json and utf-8 validations on that and the configuration backups; found no errors. Manually went through the files to the error locations and retyped the characters again; no change. Reset the device and restored the presets using the original API commands without restoring the preset backup. Nothing I’m doing is stopping this error
