INDESIGN 17.4 OR 18 DON'T WORK ANYMORE ON OS BIG SUR

Hallo there, since yesterday i can't work anymore with ID. My 22 version doesn't open anymore, the 23 never worked actually. I dont' want to upgrade my OS, i installed again the creative cloud, but i can't uninstall the 17 version. I click on uninstall... and it stays there. i try to install other versions... the 17.4.1 stays there. what can i do to work again?? thanks
