Lightning app won't load up

Hi, I’m having this issue for the second time in 2 weeks, last time I had to uninstall the app, recovered the funds but lost all channels. Since I want to avoid that, I’m trying different approaches. I’m using umbrel on a raspberry pi 4, I have a backup file up to date on Amboss but also generated by balanceofsatoshis. I also have a troubleshoot file, can I post it here or there is sentitive information? For now I tried rebooting manually, rebooting from umbrel, stopping and starting all the scripts. Thanks

EDIT: in the troubleshoot I get this line multiple times:
lnd_1 | failed to load config: /data/.lnd/lnd.conf:3: malformed key=value (node name)
