Hi @Riranta !
I would like to inform you that this is a common issue and PRO STAFF is already aware of it.
However, could you please try the following procedure?
Delete PRO Client/Application and all the files (.rar /.apk included)
Delete all the related/remaining files of PRO (e.g temporary files), you can use a free software like Ccleaner to do that in the easiest way
Download the latest and most updated client from PRO WEBSITE DOWNLOAD PAGE
If that should not fix your issue, the new client, that should be released soon,, should be able to fix it.
There is not a estimated time/specific time for when the new client will be released, however an announce will be made on the OFFICIAL PRO Discord once it will be released.
Hope this can help you, have a great day !
