Psychopy3 Error

I’ve been using psychopy now and I can run everything and it works 100% but this error keeps popping up and I have no clue why

It says Psychopy encountered an unhandled ineternal error!
wx._core.wxAssertionError: C++ assertion “(argtype & (wxFormatStringSpecifier::value)) == argtype” failed at C:\PROJECTS\bb2\dist-win64-py36\build\ext\wxWidgets\include\wx/strvararg.h(484) in wxArgNormalizer::wxArgNormalizer(): format specifier doesn’t match argument type

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File “ctypes/callbacks.c", line 234, in ‘calling callback function’
File "C:\Program Files\PsychoPy\lib\site-packages\pyglet\window\win32_init
.py”, line 661, in f
event_handler = event_handlers.get(msg, None)
SystemError: <built-in method get of dict object at 0x000001E9A9221A20> returned a result with an error set

I’ve been encountering this same problem. If I find a fix I will get back to you.

I also have the same issue. Does annybody know a solution for this problem?

Did you delete everything from your expInfo dialogue box?
