I've had this problem in Excel before, with much the same error
message.  What solved it for me in Excel was to simply 1) move a
control and save the file, then 2) go into code, move some code right
or left; add a blank line, or
do anything to make a simple code change and then save again [Note:
don't enable your macros when opening the file]...then close the file,
start it up again and enable macros and it would "fix itself".

Today I got the same error (for the first time) in Access; so...I went
into design mode on the form I was trying to run; the one that was
crashing.  Then I repeated steps 1) and 2) above, saved the "changes",
closed the form, closed Access, and then restarted Access, and when I
opened the form -- walla! all was well.

Why does this work?  Don't know, but I'm glad it does :)
