Platform:
Google Chrome 87 on Windows 10 20H2
Syspass running on Ubuntu 18.04

Additional context
According to this Line:

sysPass/public/js/app-util.js

Line 389 in aa5ff55

if (this.config.complexity.uppercase) {

Uppercase Letters will be ignored if Lowercase Letters are not Selected.

However This Line:

sysPass/public/js/app-util.js

Line 447 in aa5ff55

if (password.config.complexity.uppercase) {

Will check Uppercase even if there are no Lowercase Letters, Resulting in an Infinite Loop.

sysPass/public/js/app-util.js

Line 466 in aa5ff55

} while (!checkComplexity(outPassword));

Thank you for your Time.
