I have been using version 15 for about a week now. It has occasionally crashed without any warning or messages. Today, it often "freezes".

The freeze occurs when I have a syntax error in my SQL and click run. It takes a minute or two before I get the Error window. The status bar says "Initializing..." the entire time. When the error window appears, the status bar says "Executing...". When I click OK on the error, it takes another minute or two before the "spinning wheel" cursor goes away so I can do anything in PL/SQL Developer. The status bar continues to say "Executing..." during this wait.

My computer is not affected. I can access anything on my other monitor and move it over the PL/SQL Developer window. Everything works and performs as usual.

Eventually, the freeze ends, and I have access again. This issue needs to be resolved ASAP as I can't wait five minutes every time I type something wrong.

Windows 11 was updated last night and that update may be related to the problem.
