Installing ubuntu LTS 22-04 besides Windows 11 fails

[Thomas A. Weingartner]

On new Notebook Lenovo ThinkPad T14-Gen1 (Type 20UD006BGE) (https://support.lenovo.com/at/de/manuals/um923720-english-user-guide-html-thinkpad-t14-t15-p14s-p15s) I first installed Windows 11, worked fine.
Then Installing Ubuntu from USB-Stick, using normal procedure, option "Install Ubuntu alongside Windows", which was proposed in installing process, then changing the slider of partition-size so that windows had only 96GB (71 already used), and about 400GB for Linux/Ubuntu.
Then restart, then grub menu, selecting Ubuntu, resulted
1. in the first attachment, and then after retry in
2. the second attachment

Summary: using standard-installation procedure of Ubuntu LTS 22.04 alongside windows 11 resulted in problem with partitions or file-system.

Two additional informations:
1. Windows 11 still works, when after restart selected in the grub menu. Starts fine.
2. in Windows, the windows partition size (within explorer) is still reported as the original full size of about 500GB. This means, that partition-resizing by Ubuntu during installation has not worked well.
What shall be done now?

Bug appears right AFTER Ubuntu installation, when booting.
Bug appears also in booting recovery mode.
But I doubt that it lies in the kernel: it lies in the failed partitioning during installation procedure.

[Thomas A. Weingartner (tommyads)]

Additional Info: during Ubuntu installation, after resizing partition with the slider, I just left the pc alone, because I suppose, that any question or decision would halt the installation process and wait for my response (instead of automatically choosing some decision/answer).
As the process ran through till the end, I suppose there was no further question.

Booting back to the USB stick, please post the output of 'sudo fdisk -l /dev/nvme0n1
