PlatformIO Building hangs and does nothing.

[zekageri]

When i try to build a project with esp32 PIO is just hangs and does nothing.

This is not a freeze. Its different.

My PIO.ini:

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino

upload_protocol = espota
upload_port = 192.168.0.33
monitor_speed = 115200
monitor_filters = esp32_exception_decoder

board_build.flash_size = 16MB (128mb)
board_build.flash_mode = dio
board_build.partitions = large_spiffs_16MB.csv

I have tried to update all PIO related stuffs, deleted .vscode folder, restarted pc and clean project.

Terminal shows only that while hanging at build:

Verbose mode can be enabled via `-v, --verbose` option

Same thing when i upload via COM or IP.

[zekageri]

Other Projects are building correctly and uploading fine.

[zekageri]

If i create a new project, and copy the src and the lib and the pio.ini to the new project from the old, the issue is the same.

platformio/platformio-core#3417 (comment)

[tjhaas17]

Have you figured this out? I'm having the same problem and cant seem to find any other sources

[YiffyToys]

I seem to have the same issue "byte 0x81 in position 8" in issue #2405.
It auto update to the latest version.
You're up-to-date! PlatformIO 5.1.0 is currently the newest version available.

So this issue does NOT seem to be fixed.
