I managed to force close the channel from my node, but I could never get the Blixt wallet back online and the funds are stuck in a timelock address. No clue how to sweep.
I think you will have to use this method

if the channels are already closed, you just have to restore the seed into blixt and the sweep will be started
Ok thanks I will try again. This was about a year ago and I was unable to even seen the funds before. Is this a newer feature?
If you have only funds in onchain wallet without any channels open / pending to close, then you can use this procedure to import the wallet into Sparrow
Here I just wrote another quick guide with "tips and tricks" about Blixt.
I hope will be helpful for you.
It seems I get stuck at 100% sync but is never fully finishes. These are funds that haven’t been swept because of a force close.
check the lnd logs. Will always tell you what is going on
Is there any sensitive data in the logs? I don’t see it throwing anything major, but I have quite limited knowledge.
When I try to rescan wallet it just says blixt needs to restart, even if I totally close the app on my phone
not really, just look for errors about syncing blocks and rescan addresses
