I've just made a fresh installation of Toad For SQL Server v184.108.40.206 on my W10 (Windows 10 Pro 1903 x64 build 18362.356 ) machine and then tried to start the app, but I got the following error (see the att. for a screenshot):
Failed to save the settings for module Editor due to error Type 'System.Text.UTF8Encoding+UTF8EncodingSealed' in Assembly 'mscorlib, Version=220.127.116.11, Culture=neutral,PublicKeyToken=b77a5c51934e089' is not marked as serializable
Moreover, it seems this pop up shows up every time I try to change/save anything in the settings. I've also attached a copy of the "Editor.xml", which appears to be broken, maybe because of the above issue with the "mscorlib".
Editor.xml.txt (365 Bytes)
Any idea how to fix this without re-installing Toad?
