Strange crashes on android: com.xkcopyrightpage.Entra$O0000000.run and EdHooker_.hook

After releasing recent update of my app, strange crashes start to appear in Firebase crashlytics related to com.xkcopyrightpage package which not belongs to my app, or any of its dependencies. Said crashes now most frequent ones, overtaking by great margin crashes in my own code and used libraries combined.

I tried to google for com.xkcopyrightpage with no success.

Is my app runs under some unusual instrumentation software by someone?

Exact tracebacks:

(I definitely don't have Activity to handle such intents, and no intent to handle it)

Fatal Exception: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=mqqapi://card/show_pslcard?src_type=internal&version=1&uin=257540561&card_type=group&source=qrcode }

Again, I definitely don't have or intent to have mentioned activity in my app.
