Bitcoin Lightning payment stuck after 30 attempts, are the funds lost?

I'm using Electrum 4.4.6 AppImage on Ubuntu 22.04, I'm not using trampoline routing, and I only have one channel open with ACINQ. On December 2nd I tried to pay an invoice but the payment got stuck on the 30th attempt, so I "deleted" the payment from the list of invoices and paid with another wallet. Since then, I have had an "HTLC in current commitment transaction" in the channel details, and (apparently) I can't send more than ~0.0018 even tho I have ~0.0055...

EDIT: Payment hash: 96dd791e762253e7c11721a61e4281bc2c516f5410984099f67796d9f20d846f

Now, I thought that when the "CLTV expiry" block number was mined everything would return back to normal... but it didn't.

How can I solve this without closing the channel? (another detail is that in this state it only lets me force-close)

I'm attaching two more screenshots that may or may not provide additional information that might help you understand the issue:

This is the transaction details, note the insanely high fee...

Here's the invoice:

Thanks in advance!

No source file, test, or entry point is identified in the report. Start by reviewing the payment hash, channel details, screenshots, and CLTV state against the Lightning-channel handling; done means determining whether the HTLC and funds can be resolved without closing the channel.
