Hello Alex,
You may try to solve the problem by searching for all .EXD files(*.exd) and renaming(instead of deleting) them. Then test if the issue still occurs. If not, go ahead to delete all
.EXD files you found. Sometimes resetting up your user profile solves the issue too.
".Exd Files Are Created When You Insert Controls"
