Hi and thanks for providing more info.
Not saying it is the culprit, but WP 128 MB is a bit low± Memory Limit
WP Memory limit of 128 MB or greater (256 MB or higher is preferred)
I have even set it to 1024 M, because my host and my hosting package alows it.
Can you try move up that memory limit?
Further more I see a lot of plugins, I for one would not want/need as most of them are already provided with Elementor core:
JetBlocks For Elementor
Version: 1.1.10.1

JetBlog For Elementor
Version: 2.1.19

Jet Data Importer

Version: 1.15.16

JetMenu

Jet Plugins Wizard

JetTabs For Elementor
Version: 2.0.2

JetThemeCore
Version: 1.1.3
Author: Zemez
JetTricks
Version: 1.2.0
Author: Zemez
Kava Extra
Version: 1.0.1
Author: Zemez
Then the theme might give issues, but again, not saying it is.
Best thing to do is, disable all other plugins and see if the issue is gone.
Also switch to a default wordpress theme or my Favorite OceanWP.
I know that one just works flawless with Elementor and use it in 50+ sites.
If disabling and switching does make a difference, start enabling one by one to find the culprit.
Good luck!
