[SOLVED] Can't Boot After Resizing Btrfs Partition

Plz help me! I was on Arch Linux and used KDE Partition Manager to delete my Windows system partition (which was on the same drive). Then, I right-clicked my Btrfs partition within the tool and resized it to include the free space. After rebooting, I can't boot into my system normally, as shown in Figure 1.

My Arch Linux was installed with a Btrfs partition containing @ (root) and @home subvolumes.
I've already tried mounting the partition and checking it in an Arch live environment. Everything seems normal, and the UUIDs are correct, as shown in Figure 2.

I tried to restore a snapshot using Timeshift, but I encountered an error, as shown in Figure 3.

Re: [SOLVED] Can't Boot After Resizing Btrfs Partition

- Backed up the original data from each partition on the problematic disk.

- Booted into the Arch Live environment.

- Rebuilt the disk’s partition table and recreated the partitions to match the original layout.

- Restored the backed-up partition data.

- Regenerated the /etc/fstab file.

- Confirmed that the issue was resolved.
