Перестали работать приложения. переустановка с ошибкой

Сначала работали и Гидра и Дизайнер. Потом у Дизайнера приключился какой-то глюк, стал выдавать непрерывные ошибки. Переустановка не прошла, снес папку, стал переустанавливать - установку завершить не может, выдает ошибки. Переустановил Инсталлер, после этого перестала работать и Гидра. Снес всё, заново установил Инсталер, после этого ни один пакет из доступных бесплатных не может установиться до конца.

Ошибки в логах чаще всего такие: VMPageInstallActions 22.07.2022 8:29:55 +05:00 Error CmdExecuteAsync error: System.InvalidCastException: Can't convert of type 'System.String' to type 'System.Xml.Linq.XElement'. ---> System.Xml.XmlException: Root element is missing. at System.Xml.XmlTextReaderImpl.Throw(Exception e) at System.Xml.XmlTextReaderImpl.ParseDocumentContent() at System.Xml.XmlReader.MoveToContent() at System.Xml.Linq.XElement.Load(XmlReader reader, LoadOptions options) at System.Xml.Linq.XElement.Parse(String text, LoadOptions options) at Ecng.Common.Converter.To(Object value, Type destinationType) --- End of inner exception stack trace --- at Ecng.Common.Converter.To(Object value, Type destinationType) at Ecng.Common.Converter.To(Object value) at StockSharp.Licensing.License..ctor(Byte[] body) at StockSharp.Installer.ProfileHelper.KeepLicenseUpToDateAsync(CancellationToken token) at StockSharp.Installer.UI.VMPageInstallActions.CmdExecuteAsync()

и такие ProfileHelper 22.07.2022 8:23:03 +05:00 Error refresh license error: System.InvalidCastException: Can't convert of type 'System.String' to type 'System.Xml.Linq.XElement'. ---> System.Xml.XmlException: Root element is missing. at System.Xml.XmlTextReaderImpl.Throw(Exception e) at System.Xml.XmlTextReaderImpl.ParseDocumentContent() at System.Xml.XmlReader.MoveToContent() at System.Xml.Linq.XElement.Load(XmlReader reader, LoadOptions options) at System.Xml.Linq.XElement.Parse(String text, LoadOptions options) at Ecng.Common.Converter.To(Object value, Type destinationType) --- End of inner exception stack trace --- at Ecng.Common.Converter.To(Object value, Type destinationType) at Ecng.Common.Converter.To(Object value) at StockSharp.Licensing.License..ctor(Byte[] body) at StockSharp.Installer.ProfileHelper.KeepLicenseUpToDateAsync(CancellationToken token) at StockSharp.Installer.UI.VMPageInstallActions.CmdExecuteAsync()
