Sorry to hear that.
Firstly, you can try restoring with this seed-phrase in another wallet. I would recommend blue wallet or sparrow, or anything else you’re familiar with (remember to have taproot enabled)- this should at least give you an immediate method to access your onchain funds.
I can see in a past post you used a back-up image, would it be possible for you to please navigate to the settings dashboard and press ‘START’ under troubleshooting. If you could share the output of that here and the approximate date your node went down, we can use that to search for older lightning channel back-ups.
Let me know how you go with the above, and we can look to some next steps. Outside of that, you could always do another rescan too:
