Delay / Freeze on Sheetmetal functions or material selection

I am experiencing an issue where SOLIDWORKS freezes up for 1-2 minutes when certain Sheetmetal functions are selected. Typically, this occurs when, during sheet metal part creation, I close the base sketch and the sheet metal Base Flange function occurs. It also occurs when the Edge Flange function is selected. Also, the same sort of delay occurs when a material type is selected during assignment of a material to a part, including non sheet metal parts. The software is clearly processing something and it eventually responds, but the long delay is annoying and not something that occurred in the past.. I am using 2021 SP5.1. Computer is a Dell Precision 5560 with 32G of RAM, Windows 10 operating system.
