Cannot mix incompatible Qt library (5.14.2) with this library (5.15.1) in debian bullseye

I can’t launch any program that uses Qt since I copied some gl.so manually and/or updated debian bullseye… I don’t know.

user@desktop:~$ vlc
VLC media player 3.0.11.1 Vetinari (revision 3.0.11.1-0-g52483f3ca2)
[0000562b1d36d5b0] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
Cannot mix incompatible Qt library (5.14.2) with this library (5.15.1)

    libCgl.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libCgl.so.1

I tried reinstalling Qt, but it doesnt work, please help I can’t run many programs.

I checked bash_history and only find this, but I remember I copied other libraries to /lib/x86_64-linux-gnu/ folder:

sudo cp /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 /lib/x86_64-linux-gnu/

What should I do now? I Tried reinstalling Qt5 but it doesn’t work.
Thank you.

EDIT: I restored to a previous state with timeshift (it’s a life saver).
I don’t need anymore this post, but I think may be usseful for debian users to be answered cos I only found arch related topics with this issue.
I hope I explained myself well enough, English is not my native language.
