I am using Civi 5.38 on a WordPress site. There have been multiple custom data sets created and used for Activities which have all worked fine apart from the most recent set which needs 70+ fields adding to it. Once we get to adding 65 in the fields it seems to cause a database fault as the screen freezes when trying to add it. If I refresh the page the field then shows in the list but then none of the activities load on the homepage or show in the contact records. Is this a known limitation of custom fields on a set? When checking other forum posts there seems to be people creating upto 90 in a set so not sure what is causing this to fall over if that's the case.
