InDesign 15.1.1 crashing / very slow with Mac OS Catalina - placing pdfs

[#1]

Automatic update of Catalina last night and now having issues with Indesign - unusably slow to place and resize files - seems to be one pdf in particular. Keeps crashing. I changed the pdf to a tiff as a workaround, but it would be good to know what the problem is. Nothing wrong with the original pdf. 

Using a pretty much brand new iMac

(Retina 5K, 27-inch, 2019) 

3 GHz 6-Core Intel Core i5

16 GB 2667 MHz DDR4

Need help, please.

Hi Hannah,

Sorry to hear about this trouble. Could you please try placing the PDF into a new file and share your observations? If you want, we can take a look at your file. Please upload the PDF to Creative Cloud (or Similar service) and share the download link (https://helpx.adobe.com/in/creative-cloud/help/share.html). 

If the file is confidential, you may share it via DM.

Regards,

Srishti
