The recent Windows 11 update (KB5094126) is a known cause for issues in CAD systems.
If you are using "Draw from Coordinates" command in CadTools and get the following error: the parameter is incorrect you are probably affected by this issue.
To correct this, you can uninstall the update or search for information about your CAD system and KB5094126.
I hope next KB from Microsoft addresses this problem!
