We came across a bug, because of which we were not able to add or remove our PCF control from the Grid.
Repo Steps –
Step 1 - Add one property-set in Control Manifest when I added a single quote in the
description key and then build the solution (no error is thrown).
Example - <property-set name="sampleproperty" display-name-key="sampleproperty" description-key="Issue when using single quote example: card's " of-type-group="SupportedFields" usage="bound" required="false" />
Step 2 - Then import the solution in your environment
Step 3 – Navigate to customization to add control to your Entity Grid.

Default Read-only grid doesn’t show and Add control click event is also not working leading to which we can’t add or remove control.
If we add the control without single quote in property-set description-key and then select our PCF control everything will work as expected, but again you update the property-set description-key by adding single quote then import the updated solution then control will work as fine but in control configuration same issue which was mentioned above occurs i.e can’t add or remove control from form.
And as this workaround is not stable we would not able to use it in our PCF control development.
Thanks!
