Enabling hooks logging causes a mergeObject error

[Eligarf]

Environment Details

• Foundry Core Version: 9.269
• System & Version: DnD5e 1.6.3
• OS & Browser: Native foundry application
• Hosting: Self hosted

Describe the bug
The save changes operation of the debug flag config dialog crashes with these messages in the console:
foundry.js:3856 Error: One of original or other are not Objects!
at mergeObject (helpers.mjs:472)
at DevModeConfig._updateObject (DevModeConfig.mjs:271)
at DevModeConfig._onSubmit (foundry.js:3853)
_onSubmit @ foundry.js:3856
async function (async)
_onSubmit @ foundry.js:3853

To Reproduce
Steps to reproduce the behavior:

1. Disable all modules except Developer Mode module v1.15.2
2. Click on the Developer Mode Icon
3. Enable the Hooks checkbox
4. Click 'Save Changes'

Expected behavior
I expect to start seeing a log of hooks being fired as I interact with actors/etc.

Screenshots

I've tried deleting the module and reinstalling, no change in behavior. This affects all my worlds equally, Any assistance in helping me at least get rid of the bad data poisoning this operation would be very helpful.

Hmmm. That's unfortunate. I would advise backtracking to v1.13.2
That line looks like it deals with the compatibility warnings side of things for v10, in v9 it's useless and evidently causing issues... Sorry about that.
