[Bug]: Detected blocking call to open with args

[wwerther]

I Have A Problem With:

The integration in general

What's Your Problem

The integration worked but then suddenly started failing. Removing and reinstallation does not help. During configuraiton I get "unknown error" as reply on the frontend, so I tried to get something from the detailed logs.
The log states that i should contact the author and open a ticket.

If there is something I can help with troubleshooting, plese let me know. It's sad that there is not more debug information in the protocols (at least I don't find it)

Source (if relevant)

Checklist Source Error

• Use the example parameters for your source (often available in the documentation) (don't forget to restart Home Assistant after changing the configuration)
• Checked that the website of your service provider is still working
• Tested my attributes on the service provider website (if possible)
• I have tested with the latest version of the integration (master) (for HACS in the 3 dot menu of the integration click on "Redownload" and choose master as version)

Checklist Sensor Error

• Checked in the Home Assistant Calendar tab if the event names match the types names (if types argument is used)

Required

• I have searched past (closed AND opened) issues to see if this bug has already been reported, and it hasn't been.
• I understand that people give their precious time for free, and thus I've done my very best to make this problem as easy as possible to investigate.

Please share some more details:

• What WCS version do you have installed?
• List other custom components that you installed, including the version.
• Share the source that you want to setup.
  Thx

Hi,
I tried to run the configuration for "Germany -> Erding (Awido_DE)" and it fails after I selected the provider. It is not possible to select the city exactly.

It might be connected to issue: #2987 or #2896 because I found this message now also in my logs. So perhaps you can merge the bugs.

Besides running WCS 2.4.0 I also already tried downgrading to 2.2.0 which did not work, so I upgraded again. According to what I've seen in the two other issues it might be related to the ICS-Calendar 5.0.4 ?

Finally found it:
#2893 (comment)
solved the issue. So you're instruction to downgrade Icalendar solved the problem.

Not on my side.
Still not able to install this anymore.
