The issue you are facing:

I haven’t touched nextcloud in a couple weeks, and all of a sudden, without any changes on my end to that server, I started to encounter the issues below.

Issue #1 - When logged into nextcloud via the web interface, I get a lot of the errors in the logs below.

Error	PHP	fopen(/var/www/html/drive/data/appdata_ocusojwev2p9/appstore/apps.json): failed to open stream: No such file or directory at /var/www/html/drive/lib/private/Files/Storage/Local.php#216		2017-04-27T07:16:08-0400

Issue #2 - I can no longer access Passman, as I get the following message in a box when launching the app:

You have incoming share requests.
If you want to put the credential in a other vault,
logout of this vault and login to the vault you want the shared credential in.
Label	Permissions	Received from	Date

I close the message, and get the loading graphic, but it never advances to Passman.

Logs observed when trying to launch Passman:

Is there an issue open for this?. I am also experiencing it

Same here!

Error PHP Method OC_L10N_String::__toString() must return a string value at /var/www/nextcloud/lib/private/L10N/L10N.php#85

and

Error PHP vsprintf(): Too few arguments at /var/www/nextcloud/lib/private/legacy/l10n/string.php#72

in Logfile. But I can start Passman AND I can enter my Vault. But maybe it belongs to this problem:
