Worked: v.283.5

Short description of error
When trying to "apply all" to a certain object with the Modifier Tools addon this error is produced and the operation fails:

Exact steps for others to reproduce the error
I'm not sure how to reproduce this error as I have been working with modifier tools and this scene without issues until now. I can confirm this error does not occur if the scene is opened in v2.83.5.

I've attached the scene with only the object that causes the error. The steps to reproduce are:

Open attached blend file
Select "window pointy" object
Go into modifiers tab with Modifier Tools addon enabled and try to hit "apply all", error should result

I can reproduce this too. Applying them one-by-one still works.

This error occurs only in recent Blender 2.90 builds. The operator works in a build from August 16th and also in 2.91. Also, if you add the operator to Quick Favourites and call the operator inside the viewport, it works. Is this related to disabling experimental features in Blender 2.90 (https://developer.blender.org/D8589)?

I'd just like to point out that the bug isn't in the addon, my own addon (Modifier List) also has this issue. Calling context.copy() in Properties Editor doesn't currently work.

I wonder if this could be fixed before the release since this bug was just recently introduced? Or maybe it's too late?
