I tried several times to contact the support, but they did not recognize the error and it was simply impossible to prove something. I understood that they just troll me and this issue does not lie in the priority of developers. I decided to just roll back to version 4.17 there are no such problems, but there are still some problems as android back button does not work in 4.17. But it was fixed in 4.21 versions. I found the changes in version 4.21 and integrated it into 4.17 source. For the future I will give you an advice not to be updated so often at least once a year, otherwise there will be serious problems and a lot of work.
