Develop module completely unusable

[by sailor]

As you can see, whereas the picture is selected, it is not showing on the develop module so i can't edit it.
I tried to reinitialize as possible settings & catalogs, i tried to disconnect from internet and reconnect... This is not changing anything.
I'm using a 64Go of RAM Apple MacBook Pro 2021 with a Apple M1 Max, and I'm using the version 11.5 of lightroom.
Can anyone help me ? Thank you.

Why are you using version 11.5? The current version is 12.4.
