Use "iw phy" to check on which channels IBSS is allowed on your device.
Most likely all 5GHz channels are disallowed.
For example I have:
$ iw phy | grep "no IBSS"
* 2467 MHz [12] (15.0 dBm) (passive scanning, no IBSS)
* 2472 MHz [13] (15.0 dBm) (passive scanning, no IBSS)
* 5180 MHz [36] (15.0 dBm) (passive scanning, no IBSS)
* 5200 MHz [40] (15.0 dBm) (passive scanning, no IBSS)
* 5220 MHz [44] (15.0 dBm) (passive scanning, no IBSS)
* 5240 MHz [48] (15.0 dBm) (passive scanning, no IBSS)
* 5260 MHz [52] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5280 MHz [56] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5300 MHz [60] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5320 MHz [64] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5500 MHz [100] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5520 MHz [104] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5540 MHz [108] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5560 MHz [112] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5580 MHz [116] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5600 MHz [120] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5620 MHz [124] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5640 MHz [128] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5660 MHz [132] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5680 MHz [136] (15.0 dBm) (passive scanning, no IBSS, radar detection)
* 5700 MHz [140] (15.0 dBm) (passive scanning, no IBSS, radar detection)
