Wordpress Critical Error after Activating Plugin

[cahlenlee]

DESCRIPTION: After installing LBRYPress on my self-hosted Wordpress site (cahlen.org) and activating the plugin, the Wordpress /wp-admin URL shows a critical error. I cannot access the Plugins menu to deactivate LBRYPress, and must do so via SFTP.

This occurs whether or not the LBRY service is running on the server.

REPRO STEPS:

1. Log into self-hosted Wordpress site
2. Navigate to 'Plugins > Add New > Upload Plugin'
3. Upload 'lbrypress-master.zip'
4. Click 'Activate Plugin'

Results: Wordpress critical error and no access to /wp-admin

Expected: User is returned to Plugins menu

ENVIRONMENT: WordPress version 5.3.3 Current theme: Lodestar (version 1.0.8) Current plugin: LBRYPress (version 0.0.1) PHP version 7.2.24-0ubuntu0.18.04.4

This does not occur on another self-hosted Wordpress server I have (moderndaywizards.org). It's using the same theme as the other site, so it's not that. Here are the versions the server that works is using:

Wordpress 5.4.1 PHP 7.2.24 Ubuntu 18.04.4
