I disabled all other plugins, switched to basic theme (2017) and then the UM activation was successful. Then I activated all the plugins and my theme, so everything is ok

The same problem. When I update the plugin – the Fatal Error appears.
If I install it on a blank wordpress site, or on a site, where ultimate member was never installed – it installs and activates.
Is there any workaround?
