Hello, I am facing strange crash with the latest version 3.4.6. Do you have any suggestions?

Here is the stack trace:

Please take a look. Found the reason but the crash is bad because it is happening on opening TheoremReach.
When updating androidx.fragment:fragment-ktx:1.4.1 to 1.5.0, it results in the crash above. Not sure what is changed in the update, for now I downgrade it, but it would be nice if you can make it compatible with the newest version.
