2018 suddenly crashing after months of stability


Ever since I downloaded the 2020 Cdr trial and uninstalled it (wasn't worth it for my workflow)  2018 has started crashing after months of stability. I carried on using 2018 after quickly finding  2019  unreliable and never had a problem. I'm a long yerm Cdr user and have long accepted the occassional crash but I'm suddenly finding 2018 crashing on a regular basis - hangs and then vanishes. Crashed this morning on a simple outine trace.

Thanks, Colin.
