Problemas com a nova versão do Indesign 21.1

I installed the latest version (21.1) of InDesign (windows 10), and several problems started: disappearing text, the program crashing unexpectedly, and worst of all, the undo options became limited. After reading some forums, I tried one solution: clearing the preferences, uninstalling, and reinstalling the old version. It worked for a few hours, but then the same problems returned. I'd like to know if anyone has another solution...
