Hi,
Were you trying to execute some code at the time the error occurred, if so, were there any other errors or warnings in the log?
If you were running some code, then please share the section of the log that shows the code along with any surrounding messages.
Is this happening only for you or is it also happening for your colleagues?
Have any of you SAS product licences expired? Try running the following and check the dates to see if any products have expired:
proc setinit;
run;
Thanks & kind regards,
Amir.
