title: NetBeans 12.1 freezes for a few minutes when I try to Open a Project
body: <p>I've been having this issue for weeks now.
  Whenever I try to Open a Project or try to do anything which requires access to my files, it freezes.</p>
  <p>I tried all of the following things but to no avail:</p>
  <ol>
  <li>Downgrading it to 8.2</li>
  <li>Clearing the cache in my %APPDATA%  folder</li>
  <li>Deleting all my old projects which might be faulty</li>
  <li>Re-installing both NetBeans as well as JDK 15.0.1</li>
  </ol>
  <p>My Specs are:</p>
  <ul>
  <li>Intel Core i7 - 7700k @ 4.2GHz</li>
  <li>16.00 GB DDR4 3200 MHz RAM</li>
  <li>Windows 10 Pro Version 1909, OS build 18363.1198, x64</li>
  </ul>
  <p>Using JDK 15.0.1</p>
