Can't Save After Editing

I have had the pro version of SlideshowCK working fine but now all of the sudden when I try to save it after making changes to slides, I get an error (below)
I get it even if I just open the module and then close it.  Does not happen with anything else on the site nor on other sites with similar installs.
I downloaded the latest version and installed it but that didn't do the trick.
J4.4.3  PHP 8.1.27ForbiddenYou don't have permission to access this resource.Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

Hi
Please try to make a new slideshow module and tell me if you get the same error or not
CEd

No errors.

ok then the error is specific to the other module
do you have a lot of slides in it ? are you using the slides manager ?

Sounds I need to recreate it.

ok but you don't answer my questions I'm trying to identify the problem
