WordPress and EE are all currently up to date.

WordPress version 5.3.2
Current theme: Ryan Pro (version 1.3.13)
Current plugin: Event Espresso (version 4.10.2.p)

Hi there,
The error you are getting usually happens when you’re hitting your server’s max_input_vars.
If you open up the event editor, then open Chrome DevTools on that page.
In the elements table do Ctrl+F and type out ‘input’ into the search field, like this – https://monosnap.com/file/Enugw6yRtnr1WMJu7HahANrTti7p20
How many inputs does it show on the page? (My screenshot shows 1 of 74, so I have roughly 74 inputs).
Alternatively, you can contact your how and have them increase the max_input_vars value from the default (which is 1000) to something like 3000 and try again, the problem with doing so is if something is adding a ton of inputs to the page (we’vee seen themes add 14 thousand inputs before now) the above may not help so its good to check how many you have.

Current input count is 397. Should I increase the max value?

Yes, it’s advised to increase the limit for max_input_vars. You may need to contact your web host and ask them if they can raise that limit.

If they’ve lowered the default value below 1000 then it will be causing the above, you can check in Event Espresso -> Maintenance -> System information
Search for max_input_vars and check the value there.
397 sounds low enough not to run into that to me but it does depend on your host.
Another possible cause for this is a theme/plugin conflict. The error above is basically saying there isn’t a valid datetime object to run functions on, the specific line number referenced above is after the datetimes have been saved, meaning there should be valid datetimes there. The above can happen if you’ve reached the max_input_vars limit or something interfered with the request.

max_input_var limit is currently set to 1000. I have tested with the WP Troubleshooting tool and it occurs with only the EE plugin enabled.

You could check with your host to see if they can bump that limit to 2000.
Also, you could try temporarily switching to one of the default themes (like the twenty twenty theme).

Bumped the limit to 2500, running the default theme, still having an issue.
Error Log as follows:

Ok, so it doesn’t sound like max_input_vars is causing your issue.
I have tested with the WP Troubleshooting tool and it occurs with only the EE plugin enabled.
Hmm, strange.
Can you post the steps you took for this, please?
I just want to confirm you tested with only EE activated AND using a default theme such as twentyseventeen. It’s possible you have a conflict with both your theme and a plugin so testing with neither active would highlight this.
The reason I ask is the above error is almost exclusively a max_input_vars issue, the error you are getting is happening when EE is attempting to save the tickets on the event. It is trying to pull a value from a DateTime (which apparently it saved a little earlier without issue) for a ticket and getting no DateTime to pull the value from.
Is there any other error other than the above?
Have you modified EE at all? For example, do you have a custom functions plugin hooking into say FHEE__espresso_events_Pricing_Hooks___set_hooks_properties__date_format_strings to change the DateTime date format?
What is the date/time formate set within Dashboard -> Settings -> General?
How many ticket/datetimes do you have on this event?
The part of this that is really strange is:
I have an ongoing problem publishing a paid event. I run into the same error on free events, but can usually publish on the second or third attempt.
The fact that you can usually publish the event after updating X number of times is odd.
What type of hosting are you using? It is possible your running into a query limit when updating, although that’s is really just a shot in the dark.
