Ubuntu 22.04无法挂载ext4格式USB驱动器：‘操作已在进行中’错误求助

大家好，我在Ubuntu 22.04上遇到了一个USB挂载的问题：当我在文件管理器侧边栏右键点击我的USB驱动器选择“挂载”时，弹出窗口提示“Failed to mount USB Stick, an operation is already pending”（无法挂载USB驱动器，操作已在进行中）。我完全搞不清是什么操作在后台运行，而且这个问题是最近才出现的，我的USB驱动器格式是ext4。

希望大家能帮忙解决这个问题，谢谢！

补充排查信息 #

我执行了以下命令来收集系统信息，输出结果如下：

1. 执行 sudo lsblk -e7 -f 的输出：

2. 执行 cat /etc/fstab 的输出：

# /etc/fstab: static file system information.

3. 执行 ls -ld /mnt/usbdata/ 的输出：

drwxr-xr-x 2 root root 4096 Sep  7 13:26 /mnt/usbdata/

4. 执行 mount | grep ext4 的输出：

/dev/nvme0n1p7 on / type ext4 (rw,relatime,errors=remount-ro)
/dev/nvme0n1p7 on /var/snap/firefox/common/host-hunspell type ext4 (ro,noexec,noatime,errors=remount-ro)
/dev/nvme0n1p9 on /home type ext4 (rw,relatime)

后续状态更新 #

目前我还没找到解决办法。用GParted可以看到USB驱动器里的数据还存在，但尝试手动挂载到目录时，进程会一直卡住，没有任何反馈结果。
